The habit of presenting two different billings on the same poster made it unnecessary for the artwork to relate directly to any of the bands. BG180 was the artist's visual pun with "two-lips."
The 1st printing poster is identified by the presence of a thin blue vertical line 2" from the top in the right hand border. It was printed before the concert and measures 14" x 22".
The 2nd printing omits the above-mentioned vertical blue line and measures 14" x 21 1/8". It was printed after the concert on 9/13/1977 in a run of 3,000.
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.
