Berkeley, California: The Print Mint, 1967. Screenprinted envelopes containing five 8 x 10 in. screenprinted acetate sheets with op art design in various colors. 8 ¼ x 11 in. Very good. Item #5552
Meant for projected psychedelic light shows, The Print Mint issued these kits of colorful psychedelic op art transparencies for any hippie’s design needs. While the bright yellow ink on the outside of the envelopes has faded throughout the past few decades, the bright colors on the transparencies inside are as vibrant as when first printed. The Print Mint store on Telegraph Ave. produced underground comics including work by R. Crumb and Zap, psychedelic posters, and various design packets such as this.
