An historical black-and-white administrative map of the Second Republic of Poland showing national, voivodeship, and powiat boundaries of the country; the outline of former Galicia is still clear in the southeastern four voivodeships. Published by the Polish Central Statistical Office in Warsaw on the precise date of 1 April 1939, this map preceded the Second World War by exactly five months.
