The Catalogue Raisonné of the work of Giuseppe Capogrossi (Rome 1900-1972) presents for the first time all the painter's works up to 1949, in other words up to the birth of the sign with the works shown at the Galleria del Secolo in Rome in January 1950. Beginning from his earliest paintings, executed in around 1920, the Catalogue records in detail the artist's path towards the development of an increasingly abstract language and then the invention of his famous "signs". The volume is completed by critical essays, a detailed biographical timeline and an exhaustive bibliography which make the Catalogue an essential instrument of study for scholars, experts and art lovers.
