The Miró Collection, owned by the Portuguese State, granted to the Municipality of Porto for a period of 25 years and on deposit at the Serralves Foundation for the same period, brings together 85 works by the famous artist spanning six decades. The author of the catalog Robert Lubar Messeri — one of the world's leading experts on the work of Joan Miró — discusses the importance of the artist's work, his approach to materials, the scope of this collection and explains why he decided to organize the catalog chronologically by grouping together in single entries various works with common characteristics. Covering Paintings, Drawings and Collages, Sculptures and Sobreteixims, the catalogue provides detailed technical descriptions, an exhibition history, a bibliography and a contextual analysis of each work in the artist's career.
