This publication presents one hundred works by Sonia Landy Sheridan, who through her art has investigated the inner landscape of her own intensely creative, and often playful, mind. Sheridan is known for her experiments with the new forms of technology that sparked the late-twentieth-century communications revolution, as well as her experience as both an inspiring teacher and an artist-in-residence at the 3M Company. This retrospective view of Sheridan’s artistic production from the 1950s to the present includes her important work with various early imaging machines, such as the first color copier manufactured by 3M and early computer graphic systems.
