Just when you think every bit of Monkey Island 2 concept art has been accounted for, Steve Purcell smacks you in the face with a bit of much-needed education, this time in the form of a pencil sketch of Woodtick's exterior.
Here's a sketch done in the archaic medium of pencil for a Monkey Island 2 background. I honestly haven't played the game in so long I don't remember if I actually finished this one in markers or if Peter Chan finished it or if it was even used in the game.
The art obviously underwent some major changes before it made it to its final form, but that's Woodtick alright.
