Vtg Rare Green America's Suffolk Bitters Life Preserver Pig Shaped Glass Bottle

Description

I have seen this bottle several similar styles and colors, but the green is rare and hard to find. This is the only one I have seen online that is for sale.
There is a black line inside of the glass (pictured). It is not a crack and I am not sure whether or not it is part of the glass or something inside on the glass, but the opening is small and I didn’t attempt to remove it.
Measures approximately 9.5” x 3.5” x 2.5” all measurements taken at widest points.
Please note - This is from an estate and I am not sure of the origins or whether it is an original or reproduction.
