The art was created by Mike "Gabriel" Krahulik from Penny Arcade. And it came with these neat Magic-themed crayons!
Incidentally, the crayon "Violet Ultimatum" was named by Monty Ashley, who is also the person who's writing this Arcana. That isn't important; I just wanted to mention it because it's a pretty good pun and I'm proud of it.
Anyway! Mike Krahulik did eight Planeswalkers, and now we're going to show them to you! Click on each thumbnail to get a life-size page, suitable for printing and coloring in at home.
