The 1st printing handbill (see BG057) measures 4 7/8" x 7 15/16" and displays the image of the poster. Since only a small number have ever been found, it's possible that these pre-concert handbills were actually intended to be postcards and were simply overlooked in the back stamping process.
A variant handbill exists that explains the forthcoming poster is late because the "artist timetable misfired". On thin white paper, this pre-concert handbill simply states in typed dark blue ink the details of the upcoming concert. It measures 5 1/2" x 7 1/2".
