Which artist is known for collaborating with Andy Warhol and for using a crown motif in his work?

The artist recognized for collaborating with Andy Warhol and prominently featuring a crown motif in his artwork is Jean-Michel Basquiat. Basquiat was a key figure in the Neo-Expressionist movement of the late 20th century and gained fame for his graffiti-influenced style and poignant social commentary.

His collaboration with Warhol in the 1980s is significant not just for the artistic output but also for the blending of their contrasting styles: Warhol's commercial pop art aesthetics and Basquiat's raw, emotive approach. The crown motif appears frequently in Basquiat's work and symbolizes themes of power and royalty, reflecting his exploration of identity, race, and status.

The other artists mentioned do not share this specific relationship or thematic focus. Frida Kahlo is celebrated for her deeply personal and symbolic self-portraits, Roberto Matta is known for his surrealistic works that often explore psychological themes, and George Braque is one of the founders of Cubism, focusing on form and abstraction rather than the pop art movement that characterized Basquiat's era.
