As a side project to get a nice chart on the wall, I've been poking
around for nicely preserved historical air charts. It's slim pickins
out there as far as I can tell.

However, I found this website on NOAA:

http://chartmaker.ncd.noaa.gov/csdl/ctp/abstract.htm

It contains absurdly high resolution scans of all kinds of old maps,
including aviation. The files are are in a very efficient but uncommon
proprietary format called .sid. You can view them at the website using
the viewer they have, or download a program (for free) from
http://www.lizardtech.com to uncompress and convert the files to
whatever you like, .jpg, .tiff, etc.

Anyway, if you want a *print* of an old map, this is a great resource.
