Nice vintage National Radio Institute Alumni Association member pin. The lapel pin is goldtone metal and nicely decorated with gold lettering on blue enamel. It measures 9/16 inch in diameter and has a screw on back. Very good vintage condition.
The National Radio Institute was founded by James E. Smith, a high school teacher, in Washington, D.C., in 1914. It was purchased by McGraw-Hill in 1968 and renamed NRI Schools. James E. Smith remained as NRI chairman until his death in 1973. McGraw-Hill announced in 1999 that it would phase out NRI Schools, citing "changes in the marketplace".
