Signature looks authentic based on the others but how do you know everything else is real? I have a problem with all this because of the way people have been taking blank signed book pages (Schwarzenegger, will smith, etc..) and printing a picture or words over the blank space. Even the signature can be printed over without damage. I would want to know more about this card. See if it's possible to match it with others somewhere out in the wild. The "girl" drawing could have been made by anyone. We probably will never know for sure one way or the other because it's not hand written. Everything could have been added after the signature was made
