Sly & the Family Stone was the main attraction at this Winterland concert, allowing Bill Graham to add lesser known groups to take advantage of the band's drawing power. Southwind, an Oklahoma-based country rock band, and Ball and Jack, a short-lived, Jazz-Rock sextet that garnered a small following through the early 70's, played the headliner's following.
The handbill was only printed once before the concert and presents a calendar of upcoming Bill Graham events on the reverse. It measures 4 5/8" x 7 1/8".
There were also some pre-concert postcard mailers printed that were conjoined with the BG207 image (see BG207/208). They measure 7 1/8" 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.
