i know it's not cards and don't think it should or would be listed here on the database, but came across these slides from an eBay seller.
Looks like they have various players and team sets from multiple sports over multiple years. From what I gather they were slides used to show player images during television Sports broadcasts.
Just wondering if anyone has any knowledge of these they might want to share.
They seem pretty interesting to me, but also fairly costly it seems for many of them.
Here is a link to a random one from his eBay site.

thanks for any information on them in general.
