As you can see there is a bronze cap on the bottom where a piece would be signed. Perhaps because of the size and shape of the glass to make sure it doesn't torque on the bottom? In any case, the glass looks right to me. If it's not Tiffany, and I suspect it is, it is likely Steuben or Quezal, I make this judgement on 20+ years of being interested in studying glass.
Dimensions: 17.5" tall by 4.75" across the top and 5 across the base of the bronze. A little color variation in the bronze. Signed: Base signed Tiffany Studios New York 1045. SEE MY OTHER LISTINGS USUALLY A NICE ASSORTMENT OF ART GLASS.
