I managed to score both volumes a week or so ago 
These are unavailable in print, but for anyone interested in the atlas, Volume I and Volume II are available electronically.
Unfortunately not as part of a single document to easily download, but still there to see for anybody interested.
Thanks for posting this!
If anyone is interested, these can be downloaded as JPG's. If you number them in order, and then convert the whole stack to a ZIP (uncompressed - just archive), then you can change the ZIP extension to CBR (the format that electronic comic books use). You can open that CBR file in any comic book reader (the Comics++ app is free on the Windows store and works just fine). If you make Comics++ your default comic reader, then if you save the "book" in calibre, it will automatically open, just like a PDF or an EPUB.
EDIT: I just did this for Volume 1 and it was about 350 pages and 98mb. Took maybe an hour. Keep a strong cup of coffee nearby...
