Bizarre Guitars - Made of Leather

Has anyone ever seen a guitar made out of leather?  It would be a cool piece of art.  Imagine if the guitar was made out of leather and the strap was made out of wood!  Kind of like a car made out of rubber with metal wheels!

Leather guitars

I've never seen a guitar made out of leather, but there were those guitars that Elvis played that looked like they were leather (although they were just leather covers).

You can get fancy ones electric guitars too:

I suppose you could build a guitar from leather - you would have to impregnate it with some sort of resin and laminate it, but I don't think it would be a good idea.
