Geological Map of Europe, the Geographical Press, Columbia University, 1942. Scale 1:5,000,000. Brown and black print, 61x100cm. Extensive notes with regional cross-sections on the reverse side. Also on the back a reduced size copy of Lobek's Physiographic Map of Europe, which was also published separately, at the same size as this map. A very instructive, detailed and useful map for university students for 3 decades, it surprisingly shows only one entry on Google. Tears on intersections of folds, otherwise light wear on folds, clean and in fair to good condition.
