Two murals by British street artist Banksy have appeared at London’s Barbican Centre to mark an exhibition of the work of Jean-Michel Basquiat, a U.S. artist who achieved fame through the New York graffiti scene.

One references Basquiat’s 1982 “Boy and Dog in a Johnnypump”, showing a boy being searched by police officers. “Portrait of Basquiat being welcomed by the Metropolitan Police – an (unofficial) collaboration with the new Basquiat show,” Banksy said of the work on his official Instagram feed. 

The second depicts people queuing up to ride a Ferris wheel with carriages shaped like crowns, referencing Basquiat’s 1983 “Crown”.

The Barbican show “Basquiat: Boom for Real”, is the first large-scale exhibition in Britain of Basquiat’s pioneering neo-expressionism. It comes nearly 30 years after the artist, DJ, poet and musician who rose meteorically in 1980s New York, died aged 27 of a drugs overdose.

 Banksy, who often makes political points with his art, is also known to support causes he cares about.
