Tate Britain posters have been popping up in and around London – it looks like they’re flying the rainbow flag to celebrate the first exhibition dedicated to queer art. The show tells stories of unrequited love, scandal, secrecy and guilt, featuring works from 1861-1967 relating to LGBTQ identities – marking the 50th anniversary of the partial decriminalisation of male homosexuality in England, with paintings, drawings, personal photographs and film from artists such as John Singer Sargent, Dora Carrington, Duncan Grant and David Hockney.
