In her latest book about the art world, Sarah Thornton speaks to contemporary artists about the ways they negotiate politics, kinship and craft in their work. She'll be talking with Turner prize-nominated artist Isaac Julien at the Bookshop on 13 October.
We've put together thumbnails of artwork from almost all of the artists that Sarah interviews in the book. Some are pretty obvious (anything in a formaldehyde tank is a giveaway) but can you recognise them all? Send answers to firstname.lastname@example.org; winner gets a free pencil. Possibly even two pencils.
