A subject near and dear to my heart, woodblock prints. This shot shows woodblock prints at the bottom, the effect they have on the paper in the next row above, and then the cumulative look of the print as each block is applied, in the top row. Some blocks don't even put any ink on the print - they are used only to emboss the paper in a process called gofun, to give the print additional texture.
There were several Hiroshige prints on display, but they were in an area where flash photography was prohibited. So you'll have to take my word for it - they were exquisite. A few of them displayed the wood grain pattern I talked about a few days ago, which indicates that they were very early first-edition prints. That makes these particular prints just about priceless.
