That worked perfectly. And because you posted the folder, you do
not have to update the link every time you post something new. I would suggest that you put that link in your signature so that you don't have to repost it.
As for the scans themselves, they appear to be only at 200 dpi. Scans should be at minimum 300 dpi, though preferably at 600 dpi.
Here's the
Scanning Guide for reference. Just make sure the scan is done in 300 dpi or higher, and that Descreen (or Derasterize) is selected, if you have that option.
And thanks again for taking the time to do these scans. Every contribution helps!
