APPRAISER: Tell me about this great lamp.

GUEST: Theodor Ellert made this in 1919, World War I in Europe.

APPRAISER: This is a great example of what we call trench art, because the shaft here is an artillery shell. There are bullets all around the shade, there's a bullet for the finial here, and it's very, very elaborate. Not only did he sign his name, he put what we guess must be his favorite dog on there, "Sport," right? I think in a good auction this lamp might bring somewhere between $1,500 and $2,500.

GUEST: Great.
