Yes I looked at your iisting earlier !! No it is not and if someone told you that,, I would have said “pay me” !! It is a line drawing not a painting and is either machine done or transfer !! Is the symbol I asked about on the glass ?? You can see it in the pic above the image of the girl !!
I can also see the symbol in the listing pics so I can assume it is made in the glass !! Looks like an inverted Y inside a circle ??
Here is a link with the same lamp for $840 on Ebay.
