I love the setting of this vignette, and the Mercury glass lamp looks terrific.
I'm selling a few things on eBay myself (please check them out in the margin to the right). While I'm checking on my stuff, I did a little browsing and came across this lamp HERE
The seller has several nice photos of the lamp, and also posted this vignette, which really gives you an idea of size and scale.
Tell the seller mariposa490 sent you!
