Photographs by Clay Perry documenting artists of the avant garde Signals gallery are on display in the exhibition Migrations at Tate Britain. The exhibition explores how British art has been shaped by migration, and includes conceptual artists, such as David Medalla, who have exhibited and worked in Britain but consider themselves to be ‘stateless’ global citizens. Medalla was the co-founder of the Signals gallery in London in the 1960s, and Clay Perry photographed artists and exhibitions for the Signals News Bulletin.
