This double-sized postcard mailer was printed once before the concert and conjoins the images from BG227 and BG228. It displays a calendar of upcoming Bill Graham events on the reverse and measures 7" 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.
