This very fun-to-wear and finely made enamel on copper pin perfectly embodies atomic age design. The face of the pin is black enamel with drippy pools of iblue and white enamel on top.
The pin measures 2 3/4" at longest, with an approximately 2 inch span between the its tips. It is in very good vintage condition, with no visible flaws; I have not attempted to polish the copper on the back.
