While the project sounds neat, after purchasing the (rather expensive) book, it is a real let down. I understand the artistic notion of using blurry photographs, and I understand having the target not be the center of the photograph. However, the book ends up being nothing but pictures of random rooms with blurry people that could have been taken on any street or in random buildings. Even for people familiar with the Yakuza (via reading about them in books), Kusters' book in the hands of an average person without the qualification of the subject matter would leave them wondering what was going on. By the end of the book, there is almost nothing that identifies any scene or person as Yakuza. I had high hopes for this book going into it.
For years, there was 'Chedds' in Denver that offered "gourmet grilled cheese". Choice from 10+ breads, 30+ Wisconsin cheeses and a variety of toppings. The original went out, but a couple franchises remain I believe.
