This funky, figural mushroom pin dates to the 1970s, when Eisenberg introduced their "Artist's Series" design collection...inventive geometric and abstract designs in enamel over gold plate. This mushroom is shown in their 1973 "Eisenberg Enamels" advertisement in Vogue Magazine (See last photo).
Bobye Syverson, in a 2005 article on Eisenberg Enamels, said, "According to Harrice Miller's books (especially her second edition) some of the artists providing inspiration were: Braque, Miro, Chargill, Calder, Vesarely, Picasso and Pucci." Figural designs were also produced, such as owls, frogs . . . and mushrooms.
This neat piece measures 2.25" tall. The signature is "E" with copyright symbol on a raised, rectangular cartouche. Superb, excellent condition.
