well, okay, 2 days and I only got one bite (Thanx Gregory). Now I have to make sure nobody misses the truly spectacular details.

If you click the link above you will see a link near the top left side of the Yale page that says 'see all images'. This will open a thumbnail gallery of the cards. Underneath each thumbnail are 3 links. 4x, 8x, (both are standard jpg images.) and 'zoom'. Click on 4x or 8x and a jpeg opens in your browser. But click zoom and your browser will automatically download another kind of image file. This file is a 'MrSid' file ( the actual extension is .sid). It is much like a jpeg2000 file. It has a slide bar at the top and you can zoom in on the card till it seems as if you are examining it with a magnifying glass. Hi-rez doesn't get much better than this!

This is an image file format maintained by a company called Lizardtech and used by Yale and the Library of Congress and others, for hi-res imagery.

To view it, you will have to go to Lizardtech.com
http://www.lizardtech.com/download/dl_options.php?page=viewers
Scroll to bottom of page.

Download the free ExpressView Browser Plug-in (MrSID) for windows or OS X. Not only does it allow you to view these files in your browser, it also opens them locally. If you have an old computer that doesn't open jpeg2000 files, this plugin will do that too.

It might seem like a lot of trouble, but it's really pretty simple, and once you have the files and can view them in the Expressview app, you will find that you have a digital treasure very nearly as cool as a real deck.
