This article contains a scan of the interesting portions of the German 1941 Oberkommando der Wehrmacht official atlas for it's soldiers. Most of the atlas is scanned, but not everything, skipping the maps of North America which wouldn't be very useful. The maps of the invasion of Poland, reconstituted Hungary, Greece operations, etc. are all present.
Each thumbnail may be clicked on for a larger image. Please note that the scans are rather large, ca 1700 pixels across, so that the text on the maps may be read.
