Signing wrong Photo

A friend of mine went to a autograph show and got me a signed photo of  a former wrestler. She even took a picture of him signing the photo for me. Well, when she gave me the autograph, I looked at it and the signature didn't match the picture. I don't even know why the wrestler would even sign a picture that was not him. My question is, what do you do with a photo that is signed by someone else? Would you make it a cut signature? Any suggestions would be appreciated.
