Singer bowed to the big-picture style of early Fillmore posters in BG286. This noble savage sketch advertised Moby Grape and Spencer Davis who performed in the final days of the Fillmore West.
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.
