Query: so so...

This book was very interesting. But...simply put, not enough photos. Many of the photos included don't show any tattoos at all. Random elderly people and prisoners, jail cells, signs, etc. If you're wanting to understand the prison culture and politics, it would be wonderful!! If you're looking for an interesting photobook of people's tattoos, this is not the one to pick.
