It's official: summer has arrived at the RA. How do we know? Because the world's largest open submission contemporary art show for emerging and established artists opens tomorrow (June 7th) and runs until August 15. Among the artists showing work this year are Tracey Emin, Anish Kapoor, Gillian Wearing, Allen Jones, Jenny Saville and children's author and illustrator Quentin Blake. Now in its 243rd year the show features painting, sculpture, architecture and film raising funds to support artists.
