Tàpies' Posters and the Public Sphere is an illustrated catalogue raisonné of 245 posters by Antoni Tàpies from the 1950s to the present, as well as a large selection of illustrations that show the artist's social commitment, especially his defence of ethical and political issues, and the contemporaneity of his aesthetic vision. The prologue by Pilar Parcerisas follows Tàpies' work as a poster artist -- closely related to his career as a painter -- and interprets his works within the context of artistic, social and political history from the eruption of the avant-garde through the troubled times of recent decades.
