About Wallace Berman
Wallace "Wally" Berman was an American experimental filmmaker, assemblage, and collage artist and a crucial figure in postwar California art. Berman created Verifax collages, which consist of photocopies of images from magazines and newspapers mounted onto a flat surface in collage fashion and mixed with occasional solid areas of acrylic paint. In 1957 Berman had his first exhibition of his artworks at the newly opened Ferus Gallery in Los Angeles. Berman created a six-minute 8mm silent experimental film, Aleph, that he worked on from 1958 to 1976.
