1966 Sport Pix Football 8x10s (Need some help here)
 

I need some help with identification, maybe some of the more knowledgeable members of this great group can help me out

I was at a flea market today and picked up 6 8x10 photos- Jim Brown, Red Grange, Bronko Nagurski, Paul Hornung, Bobby Mitchell and John Unitas.

The limited research I was able to do so far leads me to believe these might be something called 1966 Sport Pix- There was a Jim Brown labelled this way that sold on eBay in the past few months.

However, I can find no other info, no scans of any of the rest of the pictures- has anyone ever heard of this product? I will post scans in a bit, but I am trying to figure out if I found something really cool, or just some junk.

Thanks- Ed
