1950s (?) Baseball RRPCs - Little Help!

[Eggoman]

I picked these up included in an older scrapbook of postcards. In all, there are 6 different baseball players, including the 2 pictured. They are "standard" RRPC postcard size.

Although the Kodak Paper backmarks indicate a 1950s or newer date, the players all pre-date that timeframe, I think.

I have Rudy York, Dave Robertson, Elam VanGilder, George Harpety, Carl Reynolds, and an unknown player (to me) in an old NY uniform.

Anyone know what they are OR are not? Any info on value - or lack thereof? Any interest in them or any additional information would be appreciated!

Your Humor is welcome, too!

Leon - I posted these here AND in the pre-1980s Section because although the RRPCs may be Post-War, the players are not. If this is inappropriate, feel free to yell at me and fix my "oops"!
