This is the inked & colored version of  madcat75's inside-cover book sketch for his copy of the first Peter & Company Collection.

I regularly sell signed & sketched copies of the book collection, and if the individual requests it (and send extra payment for the upgrade) I'll gladly ink and color the sketch as well.

"Don't let it go to your head, buddy" was written next to the original sketch for this. I'll never understand Madcat's infatuation with Chelsea, though this seems to be a recurring theme in his requests, hehe.
