Vintage Watkins Extract of Lemon Bottle is Circa 1940's-1950's. This was 2 oz. size. Watkins, back in the days of old, traveled door-to-door promoting and delivering their goods. Extract of Lemon was used in cooking but also had a medicinal use, as well. It promoted digestion, helped combat nausea, to mention a few.
This vintage piece is in excellent condition. The label of distributor is still on bottle. It still contains some of the original product, but definitely not recommended for human consumption.
A great vintage find to add to an antique advertising collection.
