Origins 1954 Topps Gray backs?

[SMPEP]

To add to Al's answer ... I think there is some consensus among advanced collectors of both sets that the 1952 Topps gray backs were NOT issued in Canada, but the 1954 Topps gray backs WERE issued in Canada.

I seem to recall reading an article a few years back about a couple guys who trekked across Canada on buying trips in the 1980's(?) and they reported they very regularly found 1954 gray backs, but they never once found 1952 Topps grey backs.

I will say I once went through a very large dealer collection in So Cal ... he had 1952 gray backs (he had no idea what they were) but despite having probably 10,000 1954 cards he didn't have one single 1954 gray back.

Anecdotal evidence for sure ... but every story I've heard confirms these findings.

Cheers,
Patrick

Ps - If you are selling 1954 gray backs - let me know. I still need a few for my set.
