BG240, promoting rock and roll revivalists Sha-Na-Na on the weekend and British band Traffic at mid-week, was one of the few Singer posters in which his lettering was relaxed enough to appear hand-forged. The collage was located in an unfamiliar spot on the left side of the poster.
The poster was only printed once before the concert, and it measures 13 7/8" x 21 5/16".
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.
