The CIA has recently declassified an amazing collection of maps held in its Cartographic Centre. A treasure trove for geographers (and historians)!
The Cartographic Centre was set up in 1941 to support the work of the Intelligence Agency, and the recent gift to the public marks the 75th anniversary of the map service. The collection released into the public domain via the Flickr web site includes 130 maps and 200 images of old cartographic tools – all of which possibly playing a part in shaping significant events in modern world history.
