Hi and welcome to the forum
As you might expect from the "MADE IN TAIWAN" embossing on the base, this is a modern imitation of a 19th century historical flask. It is not more than about 30 years old.
There are some original American flasks from the 19th century that did depict Benjamin Franklin
You will find some interest in these modern decorative bottles on ebay - I see them selling from a few dollars to perhaps 15 or so.
