The original poster was printed once before the concert. It displays Dave Mason's name above the Isley Brothers on the right side of the image. It measures 21 1/2" x 28 5/16".
A variant printing also exists (see BG276-A) that mirrors the original printing except "Van Morrison" has been added to the left of where Dave Mason's name is now blacked out. It was also printed before the concert and measures 21 1/2" x 28 5/16".
