That's a really interesting question, Z. In terms of baseball cards:
The Canadian baseball issue of 64 cards has a mix of reissued US cards with numbered fronts and new cards of the Montreal IL team [Lasorda, Alston and Amoros RCs there]. I am looking at a Canadian Lopat as I write this. It is not a 2nd generation print made from photographing an existing card, as many reprints are, but is in fact an original halftone print. You can tell because the areas of white are absolutely clear. The stock is that crappy gray stuff. The Canadian set has been well-defined and known for many years. It is numbered consecutively. As far as I know, there is no other definitively identified Canadian Exhibit issue.
There are a number of reprints known from the US run. They vary in qualities. What concerns me about the card in question specifically is the stock, which is unlike anything I have ever seen in an Exhibit product, and the printing, which looks muddier, with more gray-ish areas than the card usually has. That is indicative of a 2nd generation item. Clarity is lost and areas of shadowing increase. The dimensions also seem a bit more square than an Exhibit.
The only similar genuine issue I can think of is the Wrigley Exhibits from the 1960's but the print on those was clear and the stock, while gray, was not the same as this stuff. Also matched the dimensions of the regular set to a tee.
That is not to say the card isn't Canadian. It may be. I just don't think it is an ESCO product. Here is a picture of a Bogart card from a Canadian issue that it sort of reminds me of:
There were other arcade card makers. The hockey cards that are labeled as Exhibit products do not have American analogs and I have always wondered about them:
There are also a whole bunch of non-ESCO cards that I won't bother with here [see my site
