I recently purchased a 3.5 x 3.5 inch original snapshot photo of Ernie Banks.The photo is from the late 60's/early 70's. On the back of the photo it had his name written on it. At first glance, I didn't think much of it, since I thought whoever was the original owner...just wrote his name on the back. However, the more I looked at it, I saw characteristics that resembled his autograph. Is this Ernie Banks' autograph?
