Scott Skinner has one of the most unique collections of Japanese prints in the world because of his focus on collecting prints with kite images. This collection, however, does not have a corner on uniqueness, as we know of a Seattle collector of Japanese prints who collects only prints with images of cameras.. The point is, when collecting, one should have a focus, trying not to stray too far from the subject matter, so that you build a strong base for the collection.
