Report structure
The red Coke can design with diagonal thin white stripes and the white and blue "Coke" underline logo has been used by Coca-Cola periodically over the years. This design was first introduced in 1987 and was used until 1998. It was then reintroduced in 2011 as part of Coca-Cola's "Share a Coke" campaign and has been used periodically since then for various promotions and limited edition cans.
Our customer presents pictures Q1.png and Q2.png, showing an autographed invitation to Keith Haring's exhibition held at the casino in Knokke on June 28th, 1987. Haring's "Casino Knokke 87" is a famous mural painted on the casino's ceiling. The mural features playful figures, vibrant colors, and Haring's bold outlines.
Keith Haring was a famous American artist known for his bold and expressive drawings, many of which he created using pens on paper. He was known to use a variety of drawing tools, but the medium he used the most was the black marker pen. He preferred using this tool because it allowed him to create bold, thick lines with a consistent quality.
By comparison of Q1 with the Admitted signatures , labeled S1-S15 (refer to Figure ), we found the following common graphological cues between the signatures: On most Keith Haring signatures, the letters "K" and "H" are distinctive. Haring would often create a swoosh effect by starting the vertical line at the top, allowing it to slide to the left before curving back to the right, giving the line a faint inverted "S" shape. As an extreme case, on Figure (c), the vertical lines of the "H" on Q3 are concave, which is
In this subsection we characterize the Keith Haring signature graphologically, with reference to the questioned signatures Q1, Q3-Q9. An inter-se comparison of the verified authentic Admitted Signatures shows a very consistent writing pose with very little variations and a consistent rhythm. In other words, the angle, slant, pressure, speed, and other factors of the individual's writing style do not change much across signatures.
