The 1E3a paper
This paper is white and slightly thinner than the 1E1, but it is otherwise identical to it: same watermark, same porous grid, same symmetrical rectangular grid. I have a very hard time separating this paper from the 1E1 for all but a handful of stamps that were printed on both papers. For now, I will only show the 25c1E3a, that has colors unique to the printing on this paper. I am not surprised that Pettigiani misses this paper. The clue is that the 'cents' stamps issued in 1939 were printed on it, and not on the 1E1.
