Tallest Man In World-1960's B & W Photograph

Up for bid with NO RESERVE is this older black and white photograph of the tallest man in the world. It belonged to a friend of mine. She said he came to the A&P Grocery store in Roaring Spring, PA in the 1960's and she got this photograph as a souvenir. It is signed, Robert P. Hadlow, but I think it was signed beforehand, not sure. The man on the left in the photo is size of normal man, Robert is on the right. AUTOGRAPH on back, hard to read, almost missed it! Written in pencil. It is 3 1/2" x 5 1/2" unframed. I have it in a clear plastic baggie and will mail it with 2 cardboard pieces, one on each side. Pay pal or US postal money order only, insurance optional, all sales final, no flaws. I will mail out the day after payment is made, which is due within 3 days of auction end. Thanks!
