Our vintage concert postcards commemorate shows from Fillmore East, Fillmore West, Winterland and Avalon Ballroom.
The spare, boxy lettering style and woman in BG104 are identical to those in BG103, but the fare couldn't be more different: rocking blues vs. Big Brother & the Holding Co.
The postcard was printed before the concert. It measures 4 1/2" x 7".
There were also some pre-concert double-sized mailers printed that were conjoined with the BG103 image (see BG103/104). They measure 4 1/2" x 13 15/16".
