After the Second World War Dutch business men tried to continue their business with foreign clients as before. This was not always easy, as postal connections were disturbed. Also with the Czech capital Prague, which had been with Bohemia and Moravia a protectorate of Nazi Germany, postal connections were broken and it took a while before they were restored.
This card (letters were still forbidden to send) was sent from a flower exporter in Aalsmeer on June 9, 1945 to their client in Prague. It has a (black) censor from the Netherlands and a red English censor mark. Bottom left “K 03” was printed. Those K-numbers were made obligatory by the Germans from July 1941 and they were to be printed on all printed matters. The number indicates the printer. In this case it is De Nieuwe Meerbode in Aalsmeer.
