This was during the height of the “Space Age”/“Atomic Age” when all things “futuristic” had fully captured the public imagination, so you see that influence all over the place in art, fashion, architecture, industrial design. etc., with lots of stuff (appliance knobs, table lamps and interior decor, furniture, women’s fashion, etc.) taking design cues from things like rockets and molecular shapes.
Great stuff! (But those rocket-shaped horn buttons in the cars of the era will kill you!)
