The medal's obverse bears four tractors arrayed around the John Deere logo in the center. At top, John Deere's last 2-cylinder tracter, the model 830; at left, the 6-cylinder model 4010 which arrived in 1960; at right, a model 4630 that was introduced in the 1970s; finally, at the bottom, a 50 series tractor that was introduced in 1982.
The reverse bears calendar panel inscribed into tractor's front, lights and logo above, large tractor tires to both sides. At bottom, 1983.
The medal is not signed and Dick Johnson's reference does not list it. The most likely candidates for the artist(s) who worked on them are Gladys Gunzer and David Castruccio, who worked on other Deere medals in the 1980s, but I can't attribute them for sure. Any information confirming or rejecting my speculations would be welcome.
The John Deere Calendar medals were distributed by the Lee Wayne Company.
The circular medal measures 76.1mm in diameter and was struck in bronze by the Medallic Art Company of Danbury, Connecticut. No mintage is reported.
