A vintage glass soda mug promoting Rochester Root Beer. We see the Rochester Root Beer name etched on the front. There is a ribbed pattern at the top and bottom. This has an applied glass handle and thick heavy base.
Hallmarked by the J.Hungerford Smith Co. which was located in Rochester, New York. We would place this in the 1940s to 1950s for a time frame.
Measuring 6" high we see one small section with bites out of the ribbed area on the back of mug. There is no other damage. Perfect to pop in the freezer then fill with your favorite beverage.
