Ernesto de Sousa submits Isto é Pintura sobre Papel (This is Painting on Paper) for the group exhibition "O Papel como Suporte" at SNBA, 1977. The jury selected 3 of the 5 elements of the work. Questioning this decision, he takes his piece down at the opening and brings with him a photographer to register this action. Later that year, he publishes the pamphlet "In the manner of artistic guerrilla… or petty myths… or yet all the artist pisses is a work of art!" featuring his correspondence with SNBA's Direction Board and photos of the work's withdrawal.
