Cartoon Network has given us some of the most memorable animated shows of the last decade, from The Venture Bros. to Rick and Morty to Mike Tyson Mysteries. Standing tall among their ranks since 2010 is the Emmy Award-winning Regular Show. Created by executive producer J. G. Quintel, the hilariously surreal adventures of two slacker groundskeepers — bluejay Mordecai and raccoon Rigby — have introduced us to equally memorable characters like their gumball machine boss Benson, lollipop man Pops, Muscle Man, Hi-Five Ghost, Skips, Thomas, Margaret, Eileen, and CJ. Now all their mayhem has been captured between the covers of a new art book from Titan Publishing: The Art of Regular Show, written by Shannon O’Leary.

Containing never-before-seen art, including sketches, storyboards, and concept pieces, as well as interviews with Quintel and his crew, The Art of Regular Show promises to be the definitive word to date on the top-rated series. And the the good folks at Titan have just given us a look at its contents, which we’re sharing with you below. Check out some heretofore unpublished illustrations of Rigby, Benson, and Muscle Man, along with plenty of other whacky images, in the exclusive gallery below.

Now in stores, The Art of Regular Show is one hundred and sixty pages, and retails for $29.95. (Though it’s available for much less on Amazon.) Grab it and start prepping yourself for Regular Show: The Movie, now available digitally and coming to DVD on October 13th and to Cartoon Network on November 25th.
