ONE OF ONLY SIX (6) PENCIL-SIGNED IMPRESSIONS of the final state ("avec la lettre").
When the Erker-Presse printed an exhibition poster (like this one), they asked the artist (if he or she was still alive) to signed a few proofs. In this case, CHILLIDA SIGNED ONLY SIX PROOFS, AND THIS IS PROOF I/VI.
Printed on extremely fine Japanese-type wove paper.
In perfect condition.
ONE OF CHILLIDA'S LARGEST AND RAREST PRINTS.
