The artistic versatility of tattoo artists has frequently been overshadowed by the negativity that surrounds tattooing in general. Many tattoos are made by would-be artists who copy overused designs. A perfectly tattooed body requires the skills of a professional and talented artist, who creates a unique and personal design. These designs are often inspired by one or more of the various tattoo styles of Japanese, Maori or other tribal origin. "The Sketchbook" offers the reader a selection of 80 of these unique designs by well-known and less famous, but very promising, tattoo artists from around the world. Each artist was requested to create a sketch unrestrained by commercial demands and which reflects their own personal motivations.

The book is divided into two sections: the first comprises an explanation of how this collection was brought together, along with a brief illustrated overview of the history and various styles of tattooing. The second section is devoted to the artists, each sketch being accompanied by a biography and favorite quote.

The concept of this book was developed by Marco Bratt, a tattoo artist from The Netherlands, and his partner, Germanborn lifestyle photographer Nancy Heimburger, who also wrote the introductory chapter.
