It should be pointed out that, technically, *none* of the packs of RWS Tarot cards have *ever* had printings from the original Pamela Colman Smith images. Ever. None of the decks were done by photographic reproduction of Smith's work.
Smith did not do her work in stone lithography - the method via which the original decks were printed. She produced her original drawings on paper/board and these would have been traced (many cards per plate) on to the multiple stone plates (one for each colour) by a skilled plate-preparer. So, Pam-A, B, C, and D are all copies, if you want to look at it like that. And the tracing is the reason why there are differences between those versions of the deck - different people doing the tracing. Some did fine lines; some coarser. In fact, after the first deck, which was presumably traced from Smith's original drawings, the later plates may even have been traced from the earlier deck/s rather than the drawings! Copies of copies! We just don't know. Smith's original drawings, and all the original litho plates, have gone long since.
