Great paperweight style oil lamp.
Polish art glass 24% Lead Crystal
Estate Found - Comes in box - I don't know if the box is wrong or was used by the manufacturer for more items as the box mentions it is a Cigar ashtray.
In any case, it is clearly an oil lamp and has a Jablonski sticker
Quite Heavy! The lamp in the box weighs 2 pounds and 2 ounces
Approximately 4.5" tall and 3.9" wide
