BLACK & GREY TATTOO is divided into three parts: Traditional Black & Grey, Dark/Horror, and Photorealism. Indeed, there's cross-pollination among the different styles, but the breakdown isn't just for easier lifting of this monster collection. It is to show how tattoos with similar stylistic elements are interpreted differently by stellar artists around the world. The book also presents the fine art -- including paintings and charcoals -- of many of those featured, although the tattoos themselves should be considered fine art.
