This gouache is one of a number of works on paper which were given by various surrealist artists to Wolfgang Paalen, so that he could combine them to form four surrealist portfolios. Each comprising fifteen original drawings, they were sold at the 1936 `International Surrealist Exhibition? in London, with the aim to help fund surrealist publications. It relates to his celebrated painting `On the Threshold of Liberty?, which shows a room with walls made up of paintings. The recurring motifs of blue sky with clouds, bells suspended on a metal drape and hexagonal drums are explored throughout Magritte?s oeuvre.
