A not likely combination. Concrete Poetry and Brasil, but still there was a faithful group among the Brasilian artist who made Concrete Poetry and held exhibitions with them. One of them and perhaps the most famous among them, was Pedro Xisto. By chance i have bought a very nice publication by Xisto some 10 years ago and this is for sale at www.ftn-books.com. The books is in excellent condition and a typical artist book. Published in a limited edition and signed/dedicated by the artist and i believe this is the only one available on the internet at this moment. A rare chance to add this excellent publication to your collection.
