Discus made by Karhu
This birchwood discus, made by Oy Urheilutarpeita Ab (later known as Karhu), was presented by a team of visiting Japanese student athletes to Jussi Tossavainen, manager of the Helsinki Olympic Stadium in July 1935. Signatures on the discus include those of Naoto Tajima and Masao Harada, who would win gold and silver in triple jump one year later at the Berlin Olympic Games. The group of fifteen Japanese athletes arrived in Finland on 20 July 1935, and took part at many athletics meets in the country.
The weight of the discus is only 1.5 kilograms instead of the regulatory 2 kg.
