I have no way of knowing if this is Johnny's real signature. I looked up his sig on google and found a few close matches but who knows for sure. Harry Belefonte album is from 1960, haunting music from the barracks of the slave days, very cool. Johnny's album is from 1962 and is a great tribute album to the railroad building songs. These albums were given to me by a friend who is said to have produced the Johnny Cash album. This has never been verified.
Here is the front & back, they are both playable but pretty beat up.
