Hello! I've been getting into baseball postcards more lately and stumbled on this again (5 years later) in my collection while going through other postcards and wanted to ask before discarding it..

It looks to be a postcard of Lou Gehrig (bottom picture) and wanted to know - what characteristics of the it established this as a 1940's (junk?) postcard rather than a possible 'playing days' issue. I'm not too great with postcard stock or color so I think it probably relates to that but wanted to know more precisely how to age it.

Thanks again! -Frank
