This Singer poster was an obvious political comment on contemporary events.
The only postcards known to exist measure 4 5/8" x 7" and were cut from the BG271/272 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.
