First of all I want to thank Autograph Live for letting me join. My name is Robert ,but please call me Bob. My dad was a novice collector of Mickey Mantle and passed his love of autographs to me. I decided that I would concentrate on 500 home run hitters, and then added pitchers who had perfect games. I do have a few autographs of other baseball players that I admire. I was hoping that someone who's familiar with Mickey Mantle autographs could take a look at these two Mantle autographs that I recently acquired ,Any help would greatly be appreciated if these could be authentic, and again thank you so much for accepting me as a member. With great thanks. Sincerely Bob.   .
