This flyer is a bit mysterious! It's actually a contest entry form made to look like a ballot. Until recently, I thought it was handed out in theatres, and it still may have been (the instructions say to turn it in at your local theatre). Interestingly, there is NO mention of it in the recently-obtained GODZILLA vs MEGALON pressbook, although the prizes are the same as the ones mentioned in the sweepstakes there! It measures 5.5" x 11", and it's pretty tough to find one that's unused!
