What card is this and are these authentic
 

There is a guy that was left a ton of his father's stuff. A lot it is real and some of it is fake. I dont know what issue this Gehrig is and the 39 Dimmagio is clearly a secretarial signature, but I'm not even sure the card is good. It is a sample card back. What do you guys think?

The Gehrig is a Ray-O-Print

Offhand, the 1930 Ray O Print Gehrig looks authentic, though it's not a valuable card.
