John Mayall Postcard
Image may not exactly match item shipped.
The postcard was printed once before the concert. No poster is known to exist. It measures 4 3/16" x 7 7/16".
Some postcards were split from the double mailer that conjoined this image with that of GRN681015 (see GRN681011-A). These divided postcards have a rough perforated left edge.
