GUEST: This is a shoe that belonged to Robert Wadlow, the tallest human recorded in history. He's in the Guinness Book of World Records. It was a shoe he gave to my grandfather in 1934.

APPRAISER: And why did he give it to your grandfather? Well, my grandfather was a local merchant here in Knoxville. He was the local representative for Peters Shoes out of St. Louis, Missouri. And Peters made shoes for Robert Wadlow. And in turn Robert Wadlow traveled around on promotional tours. He came here to Knoxville in 1934. He and my grandfather struck up a nice relationship, and he was a very nice young man. And before he left, he gave him a shoe.

APPRAISER: He's from Alton, Illinois, outside St. Louis, born in 1918. He is recorded as the tallest... irrefutably the tallest man recorded. There have been other ideas of people elsewhere in the world, but there's actual documentation of him and photos. And he was an American celebrity. He had his shoes custom-made for him. They had to be. This is a size 35. A normal man's shoe today is about a ten and a half. So in the '20s and '30s it may have been about a nine and a half or so. So a size 35 was a particularly important shoe for people. Who knows where the other one is? Maybe gave it to another shoe store. He was on his promotional tour. Embroidered here in the inside is "Peters," for the shoe company. It's wearing off now, but they would have been hand-embroidered for these custom shoes. And also on the bottom, we see "Peters Diamond Brand." He came here, and he hadn't reached his full height. He was seven feet, 11.1 inches.

GUEST: Mm-hmm.

APPRAISER: He died in 1940.

GUEST: Yes.

APPRAISER: The brace that he used for his legs, because he had to be supported early on just to be able to walk and support his frame, he got a blister. And he got an infection. They gave him a transfusion, and he died 11 days later. And when he died, he was eight feet, 11.1 inches, so he had a whole nother foot to grow after here. And he was documented as still growing even at his death at 22. He died needing 12 pallbearers. His casket was ten feet long and half a ton.

GUEST: Wow.

APPRAISER: His family was worried that the body was going to be tampered with, so they interred it in solid cement, in concrete, so no one would tamper with it. This is going to be of interest to collectors.

GUEST: Oh, yes.

APPRAISER: And collectors for quirky things. I would put an auction estimate of $1,500 to $2,500 at auction. Thank you so much for bringing this.

GUEST: Oh, thank you.

APPRAISER: It's a great piece of American history.
