Our vintage concert postcards commemorate shows from Fillmore East, Fillmore West, Winterland and Avalon Ballroom.
The postcard was printed before the concert. Some copies have a smaller printer's bull's eye that was used for printing alignment at the right end of the ticket outlet strip. It measures 4 1/4" x 7 1/4".
1st printing A has a Place Stamp Here box on the reverse.
1st printing B has a Bulk Mail Permit #642 on the reverse.
