Keith Haring Sketchbook
15 May 2026
Description

Hello, I am writing to inquire about a potential item for review. I recently discovered a sketchbook among belongings stored in my late uncle’s attic. The sketchbook contains multiple original drawings and includes a postcard that appears signed by Andy Warhol and Keith Haring. According to family history, my uncle had personal romantic connections within the art community at the time, and it is possible these pieces were created by or associated with artists in that circle. While I cannot confirm authenticity, the volume of work and stylistic consistency throughout the sketchbook suggest it may warrant professional evaluation.

What does this mean?

Hello, this item is a contemporary sketchbook containing drawings heavily inspired by the visual language of Keith Haring and, to a lesser extent, imagery associated with the downtown New York art scene of the 1980s, including references connected to Andy Warhol. The pages shown incorporate recognizable Haring-style motifs such as outlined dancing figures, radiant movement lines, barking dogs, simplified cartoon anatomy, and bold marker execution. However, several important stylistic inconsistencies strongly suggest the drawings are not authentic works by Keith Haring himself. The line quality lacks the fluid confidence and rhythmic precision characteristic of Haring’s hand, and the sketchbook also includes unrelated academic doodles, portrait sketches, and amateur figurative studies that diverge substantially from his known working methods. The mixed-media execution and inconsistent artistic skill level throughout the book indicate multiple hands or a hobbyist sketchbook rather than a coherent artist archive. The inscription “fake bun” and contemporary phrasing visible in one drawing also raise concerns regarding period authenticity and context.

From a market and authentication perspective, original Keith Haring sketchbooks, even fragmentary examples, would represent extremely high-value works requiring ironclad provenance, documented chain of ownership, forensic material analysis, and review by the Keith Haring Foundation or recognized specialists. In the absence of credible provenance directly linking the sketchbook to Haring or Warhol’s circle, the work should currently be treated as derivative fan art or later imitation material rather than an authentic discovery. Decorative and curiosity value may still exist as a contemporary outsider sketchbook influenced by 1980s pop and street art aesthetics, but it should not presently be represented as an original Haring work. Based on the images provided alone, the fair market value would likely fall between $50 and $250 USD as a contemporary sketchbook/art object.
