I plated this stamp to position 8R1L yesterday. Chase classified this as a shifted transfer in his book and on the Smithsonian prints. This specimen is an earlier printing showing little plate wear. Unfortunately, the inking isn't the best. I can see signs of a shifted transfer, like the spike in the G, and the consistent spots of color above the PO and A. A second specimen of 8R1L is shown in the 2400-DPI closeup for comparison.
There also appears to be some ink smear (kiss-print?) above the top edge of the upper label block.
The most remarkable thing about this stamp is the rectangular protrusion above the upper left diamond block. This is a consistent feature for this position in the late state of plate 1, but this printing shows it with very good clarity.
What puzzles me is; why would a shifted transfer only result in about three-fifths of the top of the diamond block being replicated?
I'd appreciate your thoughts, and seeing scans of this position that any members can show.
