Great find, Joe.I think the photographs that were scanned to make the JPEG were a bit fuzzy. Also the sources themselves look like they weren't in the best condition.
Anyway, there is a shareware program called "xv" which is designed to manipulate digital images--including JPEG. You can change the sharpness, contrast, color, etc and see the results. I downloaded one of the files and played around with it to get it slightly sharper, but I don't know what I am doing. Someone with more experience with manipulating images might do better.
The program is a UNIX one, but I have heard that there is a Windows version around. I got my copy at The source You can nose around there for other platforms.
