Caricature Style Idea

I'm trying to work out a good style for doing caricatures. Finally figuring out how to create good vector line art with the Wacom. Going for a retro print sort of look here - let me know what you think.

Oh, and bonus points if you can tell me what Dribbbler this is (hint: it's not me)!

EDIT: I've decided to do a caricature for whomever guesses correctly first!
