The inclusion of detailed maps of mainland South-East Asia remained an exception to the rule in Dutch atlases. One of the most detailed maps can be found in this atlas. In 1939, various Dutch newspapers gave their subscribers and readers the opportunity to collect a world atlas that was released in installments. The order of the maps reveals that this wasn’t actually a Dutch, but a Belgian atlas. The atlas appeared for the first time from 1938 with the title Patria’s verklarende en geïllustreerde wereldatlas at the Antwerp newspaper De Dag of publishing house Patria. At least nine Dutch newspapers offered their readers to collect the installments. In this period Vietnam, Cambodia and Laos together formed French Indochina. The page opposite to the map gives geographical information about Indochina, such as population, the most important cities, soil and products.
