By this I mean that "1966" is the legal framework for ownership,Carol-Citadel-Laine enter the picture and establish ownership by specifying 1966 ~ but this was well after the first, earlier decks. There was never any reason to re-set the printing plates so any copyright for the Tarot would be on the box ~ but it isn't there.
rather than the specific publishing history. But there it is...
Stuart R. Kaplan picked "1971" as his copyright, after the fact.
"Zip" Code 1104 may well have been pre-1963 and for an area
of New York... and it does make 1963 a clear date for 5-digits.
I am sure there are people who know all of this information and
would be happy to clarify things ~ if anyone knew who to ask.
