A selection initially compiled by E.M. de Melo e Castro, visual poet and author of numerous theoretical works on this subject, on display in Serralves. The selection of works is representative of these "avant-garde artists of the 1960s", and reflects the intense production of materials - such as books, object poems, magazines, pamphlets, brochures, postcards and posters, almost entirely obtained through exchange with works by Melo e Castro. Exhibition organized by Sónia Oliveira
