The Sports Museum of Finland has presented two very nice databases of various objects produced for the 1940 and 1952 Summer Olympics. Many of the objects produced for the canceled 1940 Games were used for the 1952 Games by simply changing the year and number of the Games! If you ever visit Helsinki, I recommend visiting the actual museum at the Olympic Stadium at Helsinki.
