Coinciding with the programme for the Open Walls Conference at the Nau Bostik, the Unlock fair includes lectures, talks, book presentations and the participation of over fifty publishing companies from Europe and America.

Books and magazines on graffiti and urban art are increasingly abundant and are gaining in quality. Unlock provides the general public with a valuable international selection of publications, most of them little known.
