Pedagogical Institute Graduate graduate badge, circa 1970s.
Gilded aluminum, enamels. Somewhat lesser overall quality than the similar earlier badges in brass, but still very well made, with nice enamel. Riveted 3-piece construction, with superimposed book and state emblem. Leningrad mint mark to the reverse.
Excellent condition. Includes original aluminum screw plate marked "Leningrad Monetnyi Dvor".
