Mi.20-37 (29.07.1939/1942) B&M definitives

Registered cover sent from Prerov to an address in Slezská Ostrava. Featuring various postage stamps of Bohemia and Moravia (Mi.22, 24 & 32) tied with a Czech language 'C.S.P.' date cancel (valid up to 30th June 1940). To the reverse is a vignette depicting female dancers. The commemorative label was issued for the 10th All-Sokol Rally in July 1938. This All-Sokol Rally took place in Prague at the Strahov Stadium and was attended by over 300,000 athletes from several European countries and over 2.3 million spectators. Both the Czechoslovak army and soldiers from the states of the Little Entente took part in the rally itself. The entire gathering took place at a time of increased political tension between Czechoslovakia and neighbouring Germany and underlined Czechoslovakia's determination for unity in difficult times. The placing of this vignette to the envelope could be seen as an act of defiance. Ref: 31.10.1939
