The Happy Squirrel
Here's The Lovers from one of my 1970s RWS decks. Note the pretty red eyelids...
Looking at the scribbling in front of Eve's face that is part of the angel, I would agree that this is very probably based on Pam A (again, judging from images as presented on wopc.co.uk). Having said that, I do maintain, that images with USG copyrights on them, published as "The Original Rider Waite" very closely resembles those of Pam C.
So I am wondering, if it is indeed the case, that USG prior to 1971 copyright reproduced Pam A, and afterwards, Pam C? Again, I do not own any USG RWS, and I do not know if USG's copyright covers more than one variant
