Tom Valente is a commercial artist whose done work for places like Cracked, and more recently contributed to the Justice League of America Rittenhouse Archives sketch card series. Thanks to the Martian Manhunter Fotolog, I was directed to his blog, which offered up two illustrations of the Manhunter from Mars.
More Martian Manhunter goodness. Here's a sketch of him enjoying his favorite snack, Oreos, not those imitations, "Chocos", he has to eat in the comics. And look how happy he is to have the real thing.
