A full-color political map of the Second Republic of Poland by the distinguished geographer Eugeniusz Romer and his younger colleague Józef Wąsowicz, from about 1930. The map shows voivodeship divisions, identifies cities and towns in five size rankings, traces four types of railways and two types of roads, marks universities and religious seats, plus many spas. Included are smaller maps showing known mineral deposits, population density, primary ethnicities, postal routes, and boundaries of parishes as well as school and judicial districts. This map is one of the first to use the internationally-agreed Greenwich prime meridien in place of the long-lasting Ferro prime meridien.
