In 1985, Warhol created Reigning Queens with four ruling monarch, including Queen Elizabeth II of the United Kingdom. The image of the Queen has been reproduced more times that anyone else in history, making her an ideal subject for Warhol's obsession with fame and celebrity. The series was shown at Leo Castelli Gallery with an opening on September 20, 1985. Warhol was not too happy about it being shown in NY, thinking only Europeans could be interested in royalty.
His comment on this POST is based on his quote 'I want to be as famous as the Queen of England’. Jean- Michel Basquiat who was collaborating with him at the time teases him and illustrates with an emoji mixing Warhol’s face and Basquiat famous crown.
