There are, here in the U.S., what are called "Jumbo" copies. As has always been said, if you can have "Jumbos," then you also have "minis," but nobody markets them as such.
"Jumbos" are frequently found around the edges of a particular sheet, though not in every case.
Kindest regards, Richard
Here are a few specimens of no. 158 (with a scale) showing various sizes and shapes that result from sloppy and inexact perforating. My "imperf" is Row A, position 1. At B2 is what looks like a "jumbo". A1 can fit inside B2, confirming that A1 could have been formed by someone trimming perfs off of a "jumbo". B1 and B3 are tall and thin. Row C has a couple of nice cancels. D1 and D2 have greenish paper, I suppose because the ink ran when soaking or they ran it through the Easter egg dye. The pair at E1 has top perfs that aren't even parallel to the deign. F1 just shows a hint of a second stamp to the right. How far east were those perfs? A few others are scattered through for comparison.
Now let me go and get these out of the Crystal mounts before they get poisoned.
Everything very interesting. I'll keep searching for the "true" ones.
