Q: We own a beautiful mirror that hung in my parents’ home for many years. The decoration is cut into the glass. On the back side is a label that says “Decorative Art Mirrors, Your Home Should Come First, Torstenson Glass Co., Chicago.” Can you tell us something about this?
A: The Torstenson Glass Co. was established in 1889 and is still in business in Chicago. The company makes and distributes flat glass and mirrors. The design on your mirror suggests that it was made in the 1920s or ’30s.
