Hi maryh, your bottle is most likely a whisky bottle, a lot of them had lady-leg necks like that. If you can post a good clear photo of the base someone here may be able to give you a good idea as to the age of it.
You haven't said whether your bottle is machine-made or hand-finished, Mary Ann.
If it is a machine-made bottle, it might be worth say less than $10 as a novelty to a collector of ladysleg bottles.
If it is a hand-finished bottle, it might bring say $40-$80 based on its unusual size (16" tall).
There are (at least) three factors governing the value of a hand-finished bottle:
>Rarity (How many were made or how many survive),
>Condition (Any alteration since it came out of the annealing oven), and
>Aesthetics (Color, strike of the mold, "character" such as air bubbles and slumping, etc.)
This is my opinion based on my experience; your mileage may vary.
