Santana's draw was reflected by the reduction in size of Singer's collage to accommodate a focus on the band's name in this Fall Series poster.
The poster was only printed once before the concert. It measures 13 15/16" x 21 15/16".
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.
