The medal's obverse bears corporate building with flag at top, scenes from corporate life in ring around small raised center field bearing roman numerals from VII to XII followed by I through VI arranged in old-fashioned, semi-circular floor display style, snowflake and flowers beneath.
The reverse bears legend only. Around, · QUALITY · RESPONSIBILITY · MUTUALITY · / EFFICIENCY · FREEDOM; in center field, IN / RECOGNITION / OF YOUR PERSONAL / CONTRIBUTION / TO OUR SUCCESS / (cartouche inscribed to John F. Bozzuffi / 15 Years) / (M&M / MARS logo)
My guess is that the centerfield represent a commitment to not let work intrude into private life. Work is represented by the roman numerals indicating the time from 7am to 6pm. Private life is symbolized by the snowflake and the flowers.
This is the 15 year service medal of M&M Mars. Like Goodyear many years earlier, they Mars chose different medal designs for different lengths of service or association.
The circular medal measures 76.3mm in idameter and was struck in bronze by the Medallic Art Company. No mintage is reported.
