I have this friend named Brent Engstrom, and he's one of my favorite artists, straight-up. STRAIGHT-UP, people. He does sketch cards and illustrations for stuff you've heard of: Mad Magazine, Star Wars, Garbage Pail Kids, Wacky Packages...all the weird, twisted stuff I ate up as a kid, the weird, twisted stuff that was highly influential in making me the...person I am today. Brent's work is, as you might expect, largely weird and twisted and full of black humor. You know, kids with smiles full of rotten teeth and worms in their ears. In other words, awesomely delightful, and I love it.
He's got some horror/Garbage Pail-flavored mashup cards up on his blog. I'm posting only a couple; check out the rest and explore his site- lots of goodness abounds. And if you're in the market for a sketchcard or some such, hit him up. The dude can do anything!
