Bob, please see my post in the Mystery Card Forum:

No mystery, just easier to post images there. That is an 8x10 photo on photo paper. I have 16 of these just in the the Yzerman collection. We probably have more of other players as well. So, it's not like it wouldn't be nice (for me to have them listed here), but there were no publishers behind these, no controls ober the issuance, or anything remotely similar to how a trading card is issued.
