GUEST: It's been sitting in my house since I was born. My mom just recently told me that her mother said a guy down the street made it. (chuckles) Her mother grew up in San Francisco, and, on Church Street, and so presumably some guy down the street on Church Street made it.

APPRAISER: (chuckles) And do we know the guy's name?

GUEST: Only look on the internet in the last few days do I have a clue.

APPRAISER: Mm-hmm.

GUEST: A guy named Fred Brosi.

APPRAISER: Mm-hmm.

GUEST: But otherwise, that's pretty much all I know.

APPRAISER: Are you the one who knocked this off the shelf?

GUEST (stammering): I, I, we, there were five kids in my house. (both laughing) I don't know who did it.

APPRAISER: Aw, you're throwing another one of them under the bus. So, if you see, this lamp isn't sitting exactly flush, and there's a reason for that. At some point, this lamp was knocked over. And you can see the dent here.

GUEST: Yeah.

APPRAISER: In front, and you can see where it probably went this way.

GUEST: Oh, yeah.

APPRAISER: The lamp is Old Mission Kopper Kraft, and it's marked Old Mission Kopper Kraft. This is a die-stamped mark. And it's Kopper with a K and Kraft with a K.

GUEST: Yes, okay, all right.

APPRAISER: That's the, that's the firm's logo. And Brosi was involved with Old Mission Kopper Kraft. Does that mean that he did every lamp by hand? It's possible; I'm, I'm not sure that's true. It, what I like about this, and why I wanted to talk about this is, number one, I don't think we've had a lamp by Old Mission Kopper Kraft or any piece on ROADSHOW before. And number two, we have had lamps by Dirk van Erp on ROADSHOW. And there's a relationship between the two. They're both from the Bay Area. They both define the Bay Area style. It's a classic San Francisco look, mica and wrought copper throwing out moody, diffused light in the Arts and Crafts style. Van Erp would have been earlier. This was 1922 to '25. They only lasted three years. This is a combination of a handmade and a mass-produced lamp. For example, if you look at the bottom, this is all hand-done. This is a hand-wrought piece of copper. These hand-twisted stems end in rivets that go through the bottom.

GUEST: Oh, yeah.

APPRAISER: So you know those, those aren't for show, but the shade is more a spun shade. And those hammer marks that are on the shade are not integral to the formation of the shade.

GUEST: Oh.

APPRAISER: The shade was formed, and the hammer marks were put there afterwards to make it look like it's hand-wrought.

GUEST: Oh.

APPRAISER: So those hammer marks are real.

GUEST: Okay.

APPRAISER: These are sort of fake.

GUEST: Okay.

APPRAISER: Also, if you look on the shade, you see these little thingies? Almost make it look like the shade's riveted the way the base is.

GUEST: Yeah.

APPRAISER: But they're not; those are just little raised points.

GUEST: Ah!

APPRAISER: So this is trying to look more hand-wrought than it really is.

GUEST: Okay.

APPRAISER: Nevertheless, it's a super-rare lamp. I've seen a lot of Old Mission Kopper Kraft lamps. I've not seen this form before. They tend to be more circular. What do you feel this is worth?

GUEST: So when I looked online, I saw round ones in, like, the neighborhood of, like, $1,500, maybe $2,000, but I couldn't find anything square. So I don't know.

APPRAISER: I would estimate this for $3,500 to $4,500, and I would expect it to bring between $4,000 and $5,000.

GUEST: Okay.

APPRAISER: At auction.

GUEST: Oh, wow. That's more than I expected.

APPRAISER: It's a very nice example.

GUEST: Yeah.

APPRAISER: Well, that was from the guy down the street. (both chuckle)
