Matchbox label made in Czechoslovakia 1950’s/1960’s. The text on the label reads:”Sokol belongs to the workers”. The Sokol movement is an all-age gymnastics organization first founded in Prague in the Czech region of Austria-Hungary in 1862 by Miroslav Tyrš and Jindřich Fügner. It was based upon the principle of “a strong mind in a sound body”. The Sokol, through lectures, discussions, and group outings provided what Tyrš viewed as physical, moral, and intellectual training for the nation. This training extended to men of all ages and classes, and eventually to women.
