Muted patriotic hues dominated Mari Tepper's unusual family portrait advertising Country Joe & the Fish and Moby Grape on deflated balloons.
Our vintage concert postcards commemorate shows from Fillmore East, Fillmore West, Winterland and Avalon Ballroom.
The postcard was only printed once before the concert. It measures 4 5/8" x 7 1/4".
There were also some pre-concert double-sized mailers printed that were conjoined with the BG117 image (see BG117/118). They measure 4 5/8" x 14 1/2".
