Keith Haring, September 1986, in New York City. Photo by Joe McNally/Getty Images. It’s hard to believe it’s been over 30 years since Keith Haring left us. Yet the impact of his career continues to reverberate beyond the art world. Witness Disney and Swatch’s recent collaboration with the artist’s estate to produce a new series of Mickey Mouse timepieces, and Dr. Martens’s release of a new collection of shoes embellished with Haring icons. As for Haring’s art, most dealers and collectors would agree that it remains undervalued, especially when compared to his friends and colleagues Jean-Michel Basquiat and Andy Warhol.
