Cat Kid Comic Club On Purpose see below

Hardcover Graphic Novel: Cat Kid Comic Club On Purpose written & illustrated by Dav Pilkey. Taken out of our town library to read by my 12 yr old, when my 3 yr old saw the perfect opportunity to take a sharpie she left on her floor & the library book in his reach. He made his own modern art on the first 2 pages, it is the only "Graffiti" I can find. I replaced the book w/a new copy for our town library, we were told to keep the one of a kind... 😔 See pics above for the only damage done, otherwise book is on perfect condition.
