I had a thought this morning and checked http://www.davidrumsey.com to see if there was anything by Erwin Raisz. As it turns out, there is a copy of the 1944 Atlas of Global Geography. It's a nice book, as interesting for being an atlas at a particular time (including Japan with its occupied territories). The Living Planet - Our Natural Environment is a nice geography overview without any political overlays and it contains one of my favorite concept images:

There are also other Raisz maps there such as the Landforms of California and Nevada, but they don't show up in a search by his name (click the "related images" button on the upper-right part of the pages). It may just poor internet skills on my part, though.
