Report structure
Section summaries
01
Description of the Artwork
The submission comprises two separate landscape drawings on paper, each executed in a cool monochrome dry medium consistent with graphite pencil (grey tonal range rather than a warm brown "sepia" appearance in the provided images). Both sheets are oriented horizontally (landscape format) and present rural motifs---architecture, sloping ground, vegetation, and in one case a engaged in drawing water at a well beside a field path---constructed through a combination of soft tonal modelling, light hatching, stippled tex
02
Reverse (verso) inscriptions and visible verso characteristics (descriptive only)
Both works are documented as "signed on the reverse." In the provided images, each verso bears a pencil inscription reading "van Gogh" placed toward the central-right area of the sheet. The handwriting appears lightly applied, with a soft graphite tone and minimal pressure embossing evident in standard photography. On at least one verso, a distinct rectangular paper area is visible at the lower-left corner, appearing as a lighter, more uniform patch relative to the surrounding paper tone.
03
Notes on medium terminology and comparative method
Auction catalogues frequently use "sepia" as a broad label for monochrome works on paper, but in stricter technical usage the term normally implies a brown medium---whether ink, wash, or brown crayon---rather than the cool grey tonality visible in the present photographs. By contrast, the submitted images read more readily as graphite-based drawings, with soft tonal modelling, blended passages, and pressure-dependent line rather than unequivocal pen or wash behaviour. This distinction matters in comparative terms b
04
Geographic and corpus anchoring
Both drawings belong to broad subject categories that are compatible, in the most general sense, with the world Van Gogh inhabited: rural labour, wells or trough-like structures, field paths, cottages, modest houses, and sloping ground. Yet thematic compatibility is a very low threshold. The more pressing question is whether the drawings display enough period-specific and artist-specific character to anchor them persuasively within Van Gogh's corpus.
05
Signature Analysis
The two drawings are catalogued as "signed on the reverse." In the photographs provided, each verso bears a lightly written graphite inscription reading "van Gogh," placed in an open area toward the central-right portion of the sheet. No signature is visible on the recto of either work. The following observations are based solely on digital photography; no microscopic examination, raking light, transmitted light, or ultraviolet imaging has been undertaken.

In the close-up views provided, the inscription "van Gogh" is executed in a soft graphite line with a hesitant, comparatively weak graphic character.
Private authentication
Submit your artwork for a ConfirmArt review
Use this real case as a reference for the kind of evidence that can be organized in a private authentication report.
The public browser receives rendered pages, not a native PDF viewer or direct PDF URL. Public pixels can still be screen-captured; private commissioned reports remain controlled client deliverables.
QR verification
Traceable real case
This real case has a stable verification URL and source fingerprints. The QR code resolves to the public verification record for this case.
Only your email and service selection are needed to submit the request. Optional images, dimensions and notes can be added now or later.
Payment is requested only for the Authentication report. Catalogue search, advisory, restoration and local inspection requests are reviewed first so the scope can be confirmed.
Authentication is a human expert review. ConfirmArt may use AI for bounded research support such as database, image, book or provenance searches, but not as a classifier verdict.
