GUEST: This is my Welmon Sharlhorne.

It's called Time for Man and Beast.

And it kind of reflects how unusual life Welmon's had.

He was incarcerated in Louisiana as a child and was released from prison in his mid-teens.

Did some more petty crimes, and they put him in jail for another 20 years.

APPRAISER: Oh, my goodness.

GUEST: When he was in jail, he started creating art.

And he would give it to the other prisoners, and some of it ended up in the Smithsonian Institute of Art.

APPRAISER: Welmon Sharlhorne was born in Louisiana in 1952, and a hardscrabble life for an African American boy growing up in rural Louisiana.

I mean, he, he had so many strikes against him.

The first pieces that he did, he would create on scraps of paper, anything that they gave him.

What I like about it so much is it has all of the key marks of classic outsider art.

You have the repetition.

There's a lot going on with it.

There's so much going on with it.

And that's what I find so interesting about outsider art.

It's marker on, probably, a cardboard.

Signed center right.

He's still alive.

And he's an artist that has grown in appreciation since he's been on the market.

I was looking at some auction records, and ten, 12 years ago, they were estimated at $200 to $300 and sold for $200.

As you mentioned, he's in the Smithsonian Museum.

But he's also in the Visionary Museum in Baltimore, which is one of the ultimate museums for outsider art.

This one, because it's quite large and has everything you want to see in a piece by him, I would say at auction, I would estimate it between $2,000 and $3,000.

GUEST: That's fantastic.

APPRAISER: What'd you pay for it?

GUEST: $700.

APPRAISER: Good job and good eye.

GUEST: Thanks.

Thank you very much.
