Information on 1960s PCL Issue
 

I saw these on ebay and had to have them. But now I'd like to find out more about them. Have any of you seen these before? They're 5x7, very glossy, and blank backed. The Reese has a 1960 date stamp on the back, and Newcombe played for Spokane only in 1961. So these two seem to be from different years. Any information would be appreciated. Thanks.
