Identification help needed

[aelefson]

Hi-
I recently acquired the 4 cards scanned below and I was wondering if anyone might be able to help identify these for me. I would be interested in knowing the year and the names of these sets, as well as any additional information you can provide.

The first scan is a Bob Gibson blank backed picture with a facsimile autograph. There is a logo in the bottom right corner that appears to say LPIU.

The second scan has two blank backed cards, one of Don Drysdale and the other of Gene Autry.

The third and fourth scans show a "squeaker" type postcard (it squeaks when you press the front and back together). Who is the player? He looks very familiar to me but I cannot place him. Were other "squeaker" type postcards made of baseball players?

Thanks in advance,
Alan Elefson
