The uniface medallion bears large number 50. Around top, (GOOD YEAR logo); around bottom, FIFTY YEARS OF FRIENDLY RELATIONS
This is the 50 year version of Rene Chambellan's Goodyear series of medallions. All of these medallions came mounted to a wooden board to be hung in offices or shops that were selling Goodyear product.
Dick Johnson's reference does not list this medallion under Chambellan, in fact it does not have a reference to it at all. Like all other Goodyear medallions, this one also is not edge-marked, so both an attribution to Chambellan and to the Medallic Art Company would be a bit tenuous.
Both the lettering and the overall style make me doubt that the medallion was designed by Chambellan. A query to the Goodyear Company has remained unanswered so far. I will keep it with the attribution to the Medallic Art Company and without an artist attribution until someone with better information can correct the record.
The circular medallion measures 101.6mm in diameter and was struck in bronze by the Medallic Art Company. No mintage is reported.
