I seem to be going in circles on this one. No Secret mark or grill, no perfs and a postmark, maybe 2. BUT, it looks like the perfs were cut off one side (maybe perf12) although the stamp and margins look too complete/big to have had all the perfs cut off. Back has 2 spots that might be double paper or another layer added and on the top right corner (back), is that a repair or just a crease? Was this a giveaway at a stamp show?
