A more than 300-strong Czechoslovak group arrived in Panmunjom partly by train partly by air on the turn of July and August 1953. In the first four years of existence of the NNSC some 500–600 Czechoslovaks participated. The story of the first Czechoslovak contingent is covered in the book "The Korean Peninsula after the Armistice as Seen by Czechoslovak Delegates to the Neutral Nations Supervisory Commission" which contains over 250 photographs made by members of the Czechoslovak contingent between 1953 and 1956 and four texts about the early history of the NNSC written by Seungju Hong, Jaroslav Olša Jr., Gabriel Jonsson and Alex Švamberk. Samples of photographs were published elsewhere in Korean and Czech press, e.g. in "The Korea Times". Introductory text from the book covering history of Czechoslovak-North Korean relations and the beginning of NNSC is available online
