Wallace Berman was pivotal to the development of experimental art in California during the 1950s-70s. He is perhaps best known for works that he created using a Kodak Verifax photocopier, comprising grids of images that are virtually identical except for a few discrete, variable elements rendered by hand. Among the examples of Berman’s production held in the Sackner collection is a work on paper that displays the full diversity of techniques that the artist applied to create these variations, from drawing and watercolor to collage, frottage, and letraset. The image pertains to the Radio/Aether series (1967/1974), in which a hand holds a transmitter-radio that seems to emit or receive mass-media images, as well as esoteric messages represented as symbols drawn from the Kabbalah, a Jewish mystical tradition.
