About This Project


The Terrible Two is the first in a series of books by the terribly great team of Mac Barnett and Jory John, detailing the rivalry that erupts between Miles Murphy and Niles Sparks, two pre-teen pranksters. Can the school survive their no-holds barred prank war? I'm actually not going to tell you. That's kind of my prank on you. Burnt!

Collected here are some of my favorite illustrations from the book, along with some early concept art and cover ideas. There's even a sample of the wax seal we made for honorary pranksters! If you consider yourself an accomplished jester, I highly recommend visiting the official website of The Terrible Two, to take the prankster's oath, share your own pranks, or find out where Mac and Jory will be appearing next.

If you're interested in getting a hold of the Terrible Two... you know... for reading purposes, visit your local bookstore or buy it online at Abrams Publishing or

About Kevin

Kevin Cornell spends his days in Philadelphia, drawing made-up things. You know… like a “dog driving a bus”, or a “talking can of beets”. If you ever see a talking can of beets, tell Kevin. He's been trying to figure that one out for years.

He has illustrated several books, websites, and comics, and has been doing it for quite a long time now. There's a ton more work on his old site, if you've a hankering to see more. To see his most current sketches, comics and drawings, check out his instagram.

If you have a book you want Kevin to illustrate, please get in touch with his agent, the distinguished Steve Malk. If you wish to contact Kevin because he's behind on his payments and you need to know where to send the next toe… hmmm… send that to his agent, too.
