GUEST: I don't really know anything about the artist.

It was in my parents' home my entire lifetime.

APPRAISER: Right.

GUEST: And I know that my mom used to tell us that this picture was in her childhood home.

APPRAISER: Well, the artist is John George Brown... GUEST: Mm-hmm.

APPRAISER: ...and he was born in Durham, England in 1831.

He had artistic talent early on, but his parents decided he needed a trade, so they sent him to be a glass cutter in Edinburgh.

GUEST: Oh, wow.

APPRAISER: While he was there, he attended the, the Royal Scottish Academy... GUEST: Okay.

APPRAISER: ...so that he could keep up with his interest in art.

And by the age of 22, he decided to move to London and started painting portraits.

But he was enamored with the idea of going to America.

So in 1853, he emigrates and he settles in Brooklyn.

And we can see his signature there with the initials "N.A.

", which means that he was a member of the National Academy in New York.

As an artist, he is probably one of the most prominent genre painters in America in the 19th century.

He actually had the claim of fame to be at the important Tenth Street Studio, which was a major studio of artists that included Winslow Homer and, and Frederic Church and Albert Bierstadt.

GUEST: Okay.

APPRAISER: So he was among the best of the best.

GUEST: Okay, wow.

APPRAISER: He was best known for painting children, and he was very masterful at it.

Most of his paintings tend to feature little boys, and they tend to feature street urchins, bootblacks, and newsboys on the streets of New York.

GUEST: Mm-hmm.

APPRAISER: Often they're immigrant children.

They're wearing tattered clothes, and yet they have cheerful smiles.

GUEST: Mm-hmm.

APPRAISER: They often have a dog with them, so... (chuckling) ...it's, it's a very typical kind of thing.

And he was very prolific as a painter.

The subject here is really more unusual for him.

It's a little girl.

GUEST: Mm-hmm.

APPRAISER: And although he did paint girls from time to time, he did so more readily in the 1860s.

And this painting is probably done circa 1880, and it, of course, focuses on such a charming child, and he's really reflecting the innocence and playfulness of childhood here... GUEST: Mm-hmm.

APPRAISER: ...which was a very popular topic in the Victorian era.

The painting has a label in the back with the title, which is Making Houses of Sand.

The composition is quite interesting, because J.G.

Brown was just known for painting very realistic images of the children.

And what makes this a little more interesting is that in the background, there are all sorts of figures, and they're a little bit more abstract.

So I find that really creative in terms of his work and not something we normally see.

The painting is oil on canvas, and it's in excellent condition.

Because of the subject, I think that in a gallery, in New York in particular, the painting would sell for $150,000.

GUEST (laughing): Oh, my gosh!

(laughing) Oh, my gosh.

(voice breaking) I had no idea.

I'm gonna start crying.

I had no idea.

Thank you.

(laughing) I had no idea, oh, my gosh.

APPRAISER: It's-it's just stunning.

And when I saw it, I thought, oh I was just-- it's breathtaking.

GUEST: It's really cute now, because I have one granddaughter.

APPRAISER: Oh!

GUEST: And we live up on the water in northern Michigan... APPRAISER: Yeah.

GUEST: ...and she can be the little girl in the sand.

APPRAISER: Oh, yeah.

Oh, wow.

GUEST (choked up): It's so... Wow.

Thank you.

APPRAISER: Oh, you're welcome.

GUEST: Thank you.
