Vintage National Radio Institute Alumni Association Member Lapel Pin Gold Tone Blue Enamel Screw Back Description Small vintage National Radio Institute (NRI) Alumni Association member lapel pin featuring a gold-tone finish with blue enamel lettering surrounding a five-point star and Member banner. The star incorporates the initials NRI, representing the National Radio Institute, a well-known correspondence school founded in Washington, D.C., in 1914 that trained thousands of students in radio, electronics, and later television servicing.

Alumni pins like this were awarded or sold to graduates and members of the NRI Alumni Association, making them appealing pieces of radio, electronics, amateur radio, and technical education memorabilia. This example retains its original screw-back fastening, a style commonly used on quality lapel pins from the 1930s through the 1960s. Condition Good vintage condition with light age-related wear and patina to the reverse. Enamel remains vibrant, and the screw-back fastener is present. Please review photos for details.
