A very rare art exhibition poster by the artist Niki de Saint Phalle for the exhibition at the Kunstverein für die Rheinlande und Westefalen (Art Association for the Rhineland and Westphalia) in Düsseldorf. The exhibition took place from November 19, 1968, to January 1, 1969. The poster is in used condition, showing signs of waviness, creases, tape residue, etc. It appears to have been used during the exhibition. The poster measures approximately 79.4 cm x 59.8 cm, and the frame measures 93 cm x 63 cm. This piece has an attribution mark, I am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution
