Help identifying Yankee postcards

[marktheshark]

Hi - can anyone help in identifying any of the three Yankee postcards? I picked each of these up on eBay over the last few years not truly knowing what they are. All three are approximately 3.5" x 5.5". The first two have (I believe) facsimile signatures and blank backs. The third has "Post Card" on the back (see 4th scan), and is the same image as a Jay Publishing photo from the 60's. Any info anyone may have on any of these pieces would be appreciated.

That last postcard is from a set of about 25 cards made by Jay Publishing in 1965. I've seen others with the same autograph as the second. Not sure about the first.

Were these sold at the Stadium?

Were these sold at the Stadium?

They were sold via a variety of distribution channels. By mail, stadiums, stores, etc.
