Google found me this....
does the frame hold a magnet? And a picture of the bulb and fittings would make it clear if it's an old lamp or a newer one re wired.

Here is a link that might be useful: lithophane lamp

Thanks Lindac! Well, the frame appears to be brass (does NOT hold a magnet) but the frame appears to be tin maybe? (it DOES hold a magnet)....I've added a couple pics of the bulb and fittings as well. The link you provided of the lithophane lamp looks just like the lamp I have....so it could be the same one possibly?

Here is a link that might be useful:

Not old....appears to be the same as I pictured.
But that's not telling us who made it and what it sold for...or is selling for...I don't think you will get anything like $175...that person is dreaming!

Thanks so much, Lindac for all your help! :) Yeah- I was thinking of selling it for around $30-$40, as it is a very pretty lamp....just wanted to make sure it wasn't some antique worth way more! ;) Thanks again! :)

I think it's worth more than $30 to $40....unless the lithophane panels are plastic!

No, the panels are not plastic....it's made of some sort of plaster? What do you think a good selling price might be?

Depends on how badly you want to sell. Considering that for new ones different but similar theya re asking $105...I think you could easily ask $75 to $100...
