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 handbill was only printed once before the concert and displays a calendar of upcoming Bill Graham events on the reverse. It measures 4 5/8" x 7 5/16".
There were also some pre-concert double-sized mailers printed that were conjoined with the BG181 image (see BG180/181). They measure 7 1/4" x 9 1/4".
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.
