The Grateful Dead appeared at the Fillmore West with New Riders of the Purple Sage, a Dead spin-off band, and Southern Comfort, a short-lived rock quintet. This was the last of four posters that David Singer drew for the Dead.
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.
