1981 OPC Gray vs. White Backs
I'm working on my Dwight Evans player collection, and am struggling with the '81 OPC back variations.
I've looked everywhere on line I can think to look, and still can't solidly identify the difference between these two versions.
If you look on eBay and COMC, I see cards advertised as gray backs which look for all the world like regular OPC white backs.
Is there anyone who can scan and post images of one version of each back for a comparison?
