Singer produced this nautilus design, one of the artist's favorite symbols, for a mixed Bill Graham billing featuring blues and the creative fare of the New York Ensemble.
The only postcards known to exist measure 4 5/8" x 7" and were cut from the BG253/254 pre-concert double-sized mailer.
During his Fillmore era, from 1969-1971, Singer created more posters for Graham than any other artist. Singer's posters are notable for his use of collage, incorporating thousands of images clipped from magazines spanning several decades. He developed a format that included a stunning variety of lettering styles, applying them in close relation to the theme or subject of a poster.
