Historic authenticity is our guide, so we've got to tell the truth: We don't know who created this Streamline Doorknob style, but we do know it took to 1930s-40s homes like Mae West took to innuendo.Lest its ingredients deter you, rest assured that our Ivory and Black knobs are solid cast brass with a dense, durable plastic resin ring affixed permanently to the rim.Thin and petite, they partner with the similarly proportioned Cooper Streamline Rosette Door Set.
