My friend recently told me about this AMAZING website by the Library of Congress where you can browse and even download images of Japanese fine prints before 1915.
I assume that people who visit my website are already interested in the Japanese culture, so I thought that it might of interest to you.
Here’s the link for Fine Prints: Japanese, pre-1915 Collection.
I personally found that the easiest way to browse is to go into the “Slideshow” mode (select under the drop-down menu and click “GO”).
Enjoy!
