I love, eat, sleep, and dream about maps. Giving me an atlas or map set that I do not have is a great present. My birthday (in March) has come early due to my recent discovery of the Ryhiner Collection. Tens of thousands of maps are in the collection with many for your viewing pleasure.
The collection has maps from the 1600s and on. The focus on historical maps makes this a God sent. Go to the maps page and enjoy the cartographic ecstasy for yourself!
