GUEST: My great-great-uncle received this from the White House somehow. We don't know how he received it.

APPRAISER: Which president's administration was this in?

GUEST: We were told President Coolidge.

APPRAISER: Well, he was in the White House from 1923 to 1929, which was the Art Deco period in art history, and this is a great example of American-made Art Deco glass, of which there really isn't very much. At that point, most of the art glass makers were still working in the Art Nouveau style. The Europeans were working in Art Deco, but not the Americans. But it's good quality, and I wanted to show how you open one of the points here so that you can change the light bulb.

GUEST: Yeah.

APPRAISER: What happens with administrations is, the next president comes in, he doesn't like the way the decoration looks, and he brings in a new decorator, and I'm sure that's what happened with this. Because of its historical significance and because it is an unusual form, I would put $2,500 to $3,500 on this piece.

GUEST: Okay, well, thank you very much.

APPRAISER: Thank you for bringing it.
