I couldn't resist renaming this question.
In Scotts Catalog, between Panama numbers 403 and 404, there is a brief note titled "Popes" with two stamps illustrated and the sentences, "A set of twelve stamps picturing various Popes exists. Value, approximately $100."
Usually, when you see something like this, it indicates some doubt as to its authenticity as a Postal issue but there is no information in Scotts relating to this except that no Scott numbers were issued.
I have this set but I also have an FDC Cancel on an Airmail envelope as well as five values on a registered cover dated Oct. 4, 1956 (there's a clear Montreal received cancel for Oct. 6 on the reverse)which is about three months after the FDC date of July 2. Both of these are to the same address in Toronto.
It's a nice looking set and will be kept, regardless, but I would like to know whether it was issued for use and what, if anything, other catalogues (Gibbons, Michel) have to say about it. Our public Library does not have these for me to research.
