Expert’s take
Analysis
The AI model classifies Q1 as NON-AUTHENTIC with 98% accuracy.

The expert analysis conducted using an AI-based mathematical model trained on verified authentic signatures and skilled forgeries classified the signature on the artwork as non-authentic with 98% accuracy. This conclusion contradicts the Certificate of Authenticity from the Estate of Basquiat and Gerard Basquiat. The heatmap generated by the AI model highlighted strokes in the signature that were used to determine authenticity, all along the signature. In the comparative analysis against verified authentic pieces by Basquiat, the discrepancy in the signature of the artwork raises concerns about its attribution. Despite this, the artwork itself, depicting a man on a phone in vibrant red oil stick with a dynamic composition, holds aesthetic value. It stands out as visually appealing and could still be a valuable decorative addition to an art collection, even if its authenticity as a Basquiat piece is in question.

Valuation
Value Estimation
The AI model suggests the signature is non-authentic, despite aesthetic appeal.

The report indicates that the AI model trained on Basquiat’s signatures classified the signature on the artwork as non-authentic with 98% accuracy.

Is the Expert authenticity assessment accurate?
Yes, our authenticity assessment is highly accurate. It is not based on subjective opinions; instead, we provide tangible evidence to support our claims. This evidence consists of specific traits that are consistent across numerous verified authentic pieces, traits that are often missed even by the most skilled forgers. These authenticity cues—such as style, composition typical to an artist, stroke direction in autographs, characteristic signatures and monograms, and preferences for dedications in memorabilia—are derived from our extensive databases. Within this FAQ, we’ve included a selection of examples illustrating such cues that have enabled us to identify skilled forgeries, ones that were previously certified as authentic by professional curators relying solely on their subjective judgment.

How can you distinguish a signature made using an autopen from a genuine one with just a photo?
An autopen, a device designed to replicate signatures, follows a predetermined path to mimic handwriting. Despite its precision, the autopen process isn’t flawless and often leaves behind subtle clues that it has been used. Our expertise in this area comes from owning various autopen machines and extensively studying the marks they leave. We’re familiar with the specific traits of autopen signatures, such as uniform pressure, lack of natural variation in stroke, and consistent start and end points that human signatures rarely exhibit. By examining these telltale signs in high-resolution photos, our experts can effectively differentiate between autopen signatures and genuine hand-signed inscriptions.

How does AI-guided authentication work, and is it reliable?
AI-guided authentication employs advanced machine learning algorithms trained on extensive datasets of authenticated items, such as signatures of notable individuals or verified artworks. The process involves optimizing the images for precise feature extraction, which is crucial for the AI to learn and recognize authentic characteristics. A control dataset, a mix of verified authentic signatures and known forgeries, is used to validate the model’s performance with a high level of accuracy. This accuracy provides strong confidence in the AI’s ability to authenticate signatures and artwork, making it a reliable tool in our appraisal process.


Is forensic graphology considered a pseudoscience?
General graphology, which suggests that personality traits can be discerned from handwriting, is indeed viewed with skepticism by the scientific community. However, our service utilizes forensic graphology in a much narrower and scientifically accepted sense: we focus on the authentication of signatures and handwriting by comparing them with verified samples. This branch of forensic science is widely used in legal and law enforcement settings and is based on observable, repeatable patterns. Our application of graphological analysis is evidence-based, employing rigorous standards to match handwriting characteristics with established authentic exemplars. This method is respected and utilized in forensic investigations and is not considered pseudoscience.

How can you determine if an artwork is a reproduction just from a photo?
Identifying a reproduction from a photograph is a nuanced process that benefits greatly from technology. We have access to comprehensive records and databases that catalog verified original prints and their characteristics. By using these resources, we can distinguish handmade reproductions from original numbered prints by observing details that may not be perceptible to the untrained eye. Our AI-powered search tools analyze the photo, comparing it with high-resolution images of authentic works to find the closest match. These advanced algorithms look for specific markers and inconsistencies that are typical of reproductions, allowing us to deliver reliable results based on extensive data and sophisticated technology.

Where do you source the images of verified authentic samples for comparison?
Our collection of verified authentic samples for comparison comes from a variety of reputable and authoritative sources. These sources ensure that our comparisons are based on the most accurate and reliable images available, giving you confidence in our authentication process. This includes:
- Private Image Databases: We access high-quality, proprietary databases that are often costly and exclusive, ensuring we have a broad selection of authenticated images to use for comparison.
- Catalogue Raisonné: These comprehensive, annotated listings provide documented and photographed works of artists and are an invaluable resource for authentication purposes.
- Museum Collaborations: We partner with museums and other cultural institutions, which allows us to compare artworks and signatures against their vast collections of authenticated pieces.
- Auction Houses: We also obtain verified samples from past auction catalogs, where artworks and autographs have been authenticated by experts.

Do you issue Certificates of Authenticity?
Our Complete Report serves as a comprehensive Certificate of Authenticity (COA) and goes beyond by offering evidence-based conclusions, not merely opinions. The report itself is a detailed document that substantiates the authenticity of your piece with concrete findings.
However, should you require a traditional COA for marketing or other purposes, we are pleased to provide one. This certificate will be signed by Roi S., PhD, and will reference the detailed findings in your Complete Report. This formal COA, also numbered and with a unique hologram, can be requested when your artwork receives an AUTHENTIC verdict based on our rigorous examination process.

Do your appraisals comply with international standards?
Yes, our appraisals rigorously adhere to internationally recognized standards, ensuring that our evaluations are both accurate and ethically responsible. We align our practices with the AIC (American Institute for Conservation) Code of Ethics, and we follow the guidelines set by the Uniform Standards of Professional Appraisal Practice (USPAP). Our methods also comply with SWGDOC and ANSI/ASB Standard 35.
