description from a section of the wiki page for this painting, linked in the immediate reply:
A Pile of Crowns for Jean-Michel Basquiat was painted on a triangular canvas, like a warning sign, edged with a red outline.[6] In the center is a towering pile of black and white crowns on the ground glistening triumphantly. The three-pointed crown was Basquiat's signature artistic motif.[4] It appears so often in his artwork that it has become a recognizable symbol in popular culture.[7] On the bottom right corner is a copyright symbol, which was one of Basquiat's signature symbols. Haring used the triangle style motif in his limited edition screenprint run Silence = Death released in 1989 which aimed to raise awareness of the HIV/AIDS pandemic of the time.[8]
