The handbill was only printed once before the concert and presents a calendar of upcoming Bill Graham events on the reverse. It measures 4 11/16" x 7 3/16".

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.
