The medal commemorates the tenth anniversary of the National Broadcasting Company which was founded in 1926. It was distributed to its employees in 1936.
From Chris Bach, whom I owe big thanks for information about art medals, I learned the following:
This scarce Art Deco medal has long been "unsigned" in various auctions with no artist or sculptor identified or credited with the design. However, the Cleveland Museum of Art credits the medal as being a collaboration of three people: "modeled by Julio Kilenyi (American, b. 1885); obverse designed by Richard A Loederer (American, b. 1894) and the reverse designed by E.P.H. James (American)" - a gift to the museum's collection by the National Broadcasting Company in 1937 (No. 1937.9.A/B). A specimen at the New York Historical Society in NYC also credits Julio Kilenyi; and the Library of Congress collection identifies a similar item designed by Loederer in their NBC History Files: 1922-1986, Folder 173, Logos, "Photo of tenth anniversary (1936) plaque designed by Richard Loederer of Vienna."
I have only ever seen a bronze variant once. It is usually the silver-plated variant that comes up for sale.
This medal measures 76mm in diameter and was struck in bronze and silver plated bronze by the Robbins Company of Attleboro, Massachusetts.
