Hi I did not sign this glass, its too delicate to even think of putting on ebay. I am currious of it if you could see it you would understand some of it is etched and some of it cut the birds are cut, how it was done is a mystery to me as it is so very thin. My husband thought it had to be plastic because it is so thin but it is glass I bought it because I liked it, although I do not usually buy this sort of glass.
