This special mid century modern exhibition poster is a real find for any serious Jack Bush collector, dealer or scholar. It was published on the occasion of his 1966 exhibition at the Andre Emmerich Gallery. (Emmerich would later sell his gallery to Sotheby's before he passed away). This offset lithograph poster/invitation was mailed to the director of the McNay Art Institute in Texas, and bears the 1966 stamp and postmark. Please look carefully at the photographs. This is in vintage, good, stable condition. It has the original folds.
