Collage artist Wangechi Mutu has rallied the art world in New York City, London and throughout Africa to lend their voices to a new campaign to change perceptions of Africa today and unite Africans all over the world. She has co-founded Africa's Out!, a platform that holds exhibitions, events and discussions to showcase and interrogate the diversity of African creativity. Its first event is an exhibition of work by more than 40 renowned artists at Gladstone Gallery in New York. The artists have each selected one piece of work to auctioned at the event, with funds going to support the work of UHAI - the East African Sexual Health and Rights Initiative, an NGO that advocates for the rights of sexual minorities in East Africa.
Here 14 artists show us the piece they selected and tell us why they got involved:
