On her head, she’s wearing an extravagant hat topped with dyed ostrich feathers. But it’s the dress that grabs the viewer’s attention. Its endless squares, rhomboids, and triangles make Victor Vasarely’s IMPHY, which is dated 1956–57, a fascinating piece. The eye and the mind struggle to find some logical progression, but the shapes exist within a magical space where very different rules apply. Other works in the exhibition: From the series Ladies & Gentlemen, by Andy Warhol, Untitled by Joseph Beuys, two works by Niki de Saint Phalle and a Front Store by Christo from 1964-65.
