Hi guys..I was looking at all my map stamp and came across an interesting perforation oddity...All (most) map stamps have a perforation of
12.0 x 12.0...I have come across 2stamps that have a perforation of
12.15 x 12.0...With the amount of analysis I have done, I have concluded that 82.5% of map stamps have a top perforation of
12.0 x 12.0 and 7.5% have a top perforation of
12.15 x 12.0Robert
THE STAMPS BELOW WERE LINED UP FROM RIGHT TO LEFT.
