The research for this catalogue raisonné of paintings began in 1957. The artist himself and later the Miró estate were largely involved in its preparation. This catalogue of paintings has been established by Jacques Dupin, Ariane Lelong- Mainaud and Joan Punyet Miró. The catalogue includes all the artist?s oils, acrylics, and works in various media on canvas, cardboard, wood, masonite, copper and other hard supports. In the six volumes ?all published only in english? all paintings are reproduced in color, whenever possible, accompanied by their title, date, technique, and dimensions, with indication of signature and inscriptions on the back, as well as their collection, provenance, important exhibitions and major publications in which they are reproduced.
