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 5" x 7".
There were also some pre-concert double-sized mailers printed that were conjoined with the FD146 image (see FD145/146). They measure 6 1/2" x 9 1/4".
