In the collection of the Museum of Cieszyn Silesia in Cieszyn there is a propaganda film dating from september 1919 and made for the planned referendum concerning the future of Cieszyn Silesia after its division between Poland and Czechoslovakia. The piece lasting 14 seconds shows ul. Zamkowa and the Main Bridge (today the Friendship Bridge) with the tram. The author would like to thank Sławomir Szewieczek for the conversion of the film from a video tape.
