Comic books have a tradition of "crossovers," where characters from a completely different story make a surprise appearance. In some cases the results seem forced or out-of-keeping with the story. Fortunately, with this book, such is not the case. In this book, the creators succeed in making a humorous and interesting blend of the Mask character (as seen in the movie of the same title) and the Joker. Also, the other characters (Batman, Commissioner Gordon, et al.) stay in character, as the wacky Joker/Mask bounces off the walls, and wrecks general mayhem.

I got this book for my eight-year-old son, and must admit that we both loved it. The story is funny and yet gripping, and the graphics are well done. We both highly recommend this book to you.
