This ambitious portfolio by Antoni Tàpies comprises a monotype and 24 etchings that showcase the artist's experimental approach to printmaking through the incorporation of unconventional materials such as carborundum, resins, and collage elements. The twenty three colored works on Arches paper are accompanied by texts from the medieval philosopher Ramon Llull, establishing a conceptual dialogue between visual abstraction and philosophical inquiry. The complete ensemble, presented in handmade paper wrappers and a cloth covered portfolio box with screenprinted decoration, exemplifies Tàpies' commitment to treating the book as a total artwork rather than merely a vehicle for images.
