Kacho or Kacho-ga (Bird and Flower) prints remain one of the dominant themes in ukiyo-e and shin hanga prints. Almost every artist has a few kacho prints under their belts, and these prints can fetch quite a lot of money on the market today. One of the reasons kacho prints are so valuable is that there are not many left in fine condition these days, the reason being, that people actually hung these prints up on their walls for decoration. As a test, hang a picture up on a wall and expose it for 250 years to cigarette smoke, chimney smoke, kitchen smoke, dust, and sunlight. Step 2: see how it looks!
