Thanks everyone! Really glad to hear the positive feedback. This is my first Mantle autograph and happy to finally add one to my collection. I always get nervous with autographs from Mantle,Williams, Ruth,Dimaggio etc.
When I received the photo, I noticed at the bottom of the frame it looks like a Mickey Mantle "M" ( I circled it in red and turn up the contrast ) had been started. It had me a little worried, but appears that was probably just a goof on Mantle on where to sign. Rather than someone practicing his autograph.
