Contemporary card of a 1938 poster, mailed in 2019 with stamp, postmark, and Priority label.  Our sense of Olympics history is not too good, so we checked Wikipedia, and learned “The 1940 Summer Olympics … were originally scheduled to be held from September 21 to October 6, 1940, in Tokyo.  They were rescheduled for Helsinki, to be held from July 20 to August 4, 1940, but were ultimately canceled due to the outbreak of World War II.”  So that accounts for the rings.  Grade: 1
