These are mainly digitally enhanced plates from the book by Leonard West. You can get the original here;

As a rule, the scan with the most downloads will be the best quality. Google scans are usually useless.
I got some better plates and also managed to enhance them, so I changed the images. If you checked back and thought something was "off" it's not your eyes, they are different plates! :)
