So the questions are (for me at any rate): Does the Papess intentionally incorporate, as part of its design, the symbolic representation of a penis? To which I would without hesitation reply in the negative.To enjoy such diversions is to be entertained even as the cardmaker might have been; to attribute greater significance to such side-shows is to forget about Tarot.
On the other hand, do some decks, such as the Conver, possibly display that the woodcutters, seeing something more than intended, decided to even accentuate this as a bit of a private 'joke' that has no symbolic intent (other than the equivalent to what RAH posted above)? I would answer in that it is likely, and if not in this specific case, we should certainly be able to find such examples in other decks made, it should be recalled, for the mass market, and not carefully handpainted for the privileged.
