1c Blue, Ty. IIIa (22). Position 46L12, unused (no gum), wide margins, attractive color, Very Fine, a scarce unused example of this desirable Plate 12 position, according to the Neinken book (p. 495), Position 46L12 is different from all other positions on Plate 12, it should be a B Relief, but the bottom left of 46L12 is more complete than it should be if the entry was made from the B Relief, Neinken states that after much study by himself and Elliott Perry, they concluded that it is an exact match for the T Relief used to enter the top row of Plate 11, which was created around the same time as Plate 12, Neinken theorizes that the siderographer used the T-A-B transfer roll (used for Plate 11), and entered a single position on Plate 12 -- 46L -- perhaps to correct an earlier mistake in entering the position, other students disagree with the idea that the T Relief was used, and the matter awaits resolution, with 1975 P.F. certificate
