Steel knobs like this pair were very common during the Art Deco era. They were affordable by the middle class and rural community. The knobs were backed with either stamped rosettes or plain back plates. During the 1920s and 1930s, knobs often had a circle pattern. This set has one circle, so to speak.
Each knob measures 2 1/4 inches across and one inch deep. The set is in very good condition; there are not dings or dents.
A spindle and two set screws are included. This set is ready to use.
