The book produced on the occasion of the exhibition dedicated to Joan Miró and Alexander Calder documents all works on display from the Collections of the Portuguese State, in the custody of the Municipality of Porto and in long-term deposit at the Serralves Foundation, together with an important group of works by the two artists loaned by Fundació Joan Miró, Barcelona.

It also features a new essay by Robert Lubar Messeri, curator of the exhibition and a text by Joan Punyet Miró on the complicity and friendship between these two artists.
