Whitman did a nice job marrying the modern art style while making the content just a little reminiscent of the Adam West series.
I must say as a kid, I really dug this book, probably why I still have it as an adult. Most of the colouring is by yours truly but I'll explain that later.
The Joker, who is drawn to look like an eery combination of Phyllis Diller and that "Madame" puppet, embarks on a series of seemingly meaningless crimes that make people cry, like stealing this kid's report card and swiping some schlub's petition.
In the end, the Dynamic Duo get the best of the Joker by duping him into accepting a cheque as ransom for Robin. The dynamic duo get all dressed up to pick him up for his trip back to the asylum. Life is swell in Gotham city.
Got a colouring book you'd like to guest review? Drop me a line!
