I've already created the initial comp with colored pencils that the client signed off on, and here I'm tracing the outlines onto tracing paper so I can transfer it to the scratchboard. (no this photo is not sideways, I create most hand-drawn artwork at a 90 degree angle.)

Scratchboard is basically heavy paper covered with a thick layer of white clay, then painted with a layer of black ink, so you can "scratch" off the ink revealing the white clay underneath. You get cool "negative" artwork this way and get lots of cool little scratchy lines for a nice grungy look that we in Seattle love.
This year's artwork is inspired by the little pirate portraits in the queue at Pirates of the Caribbean Ride in Disneyland.
I went to the University Bookstore to buy a big sheet as I do every year, only to find that they recently discontinued it! In shock, I staggered over to the "clearance" table, and found that they put their whole kitty on the table, for half off! So I scored something like 7 giant 18"x24" sheets for only $7 a sheet! So I can do seven more posters before I retire.
Below: My art director (and future shoulder decoration of the pirate) inspects the work thus far. You'll also notice the pirate's face has been modified a bit. I'm using a certain next-door-neighbor's likeness, especially his waxen moustache.
