Art of Pibble - Pit Bull Coloring Book. Coloring books are no longer just for the kids. In fact, adult coloring books are all the rage right now. Researchers and art therapists alike tout the calming benefits of coloring and what better subject matter to color than beautiful Pit Bulls? This coloring book consists of 15 hand drawn images of beautiful Pit Bulls for you to color. Any watermarks or logos seen on the photos will not appear on the pages. The paper is 67 lb card stock and will accept colored pencils, markers, and/or crayons; my personal favorite is colored pencils.
