The listing, Vintage Pin: 1952 "XVIII International Conference TORONTO" Red Cross has ended.
Vintage pin from the ICRC's 1952 18th International Conference in Toronto, Ontario. The XVIII International Red Cross Conference was held in Toronto, July 23 to August 9, 1952.
This pin is in excellent shape - *very* little oxidation on back near soldering points. Imprint on back of pin reads "Birks" (my guess is that it's the high-end Canadian jewellery store). It measures (approx) 1 3/8" high by 1 1/16" wide.
