Mine was an awful "copy" too, that I got from the CC when they gave them out free. One of the reasons why it's awful is I don't think it is a copy of an original, it is a print off of a bad microfiche...no copy machine ever made such a bad print, but off of a microfiche? Sure. I believe that.
For you youngsters out there, microfiche is basically film storage "analog" copies of paper originals...
I heard the San Diego crowd was discussing this and JonnyB asked if I had one so I sent my original bad TIFF file I got from the CC. To what end the SD crowd is working this, I don't know...
