First Ever Cheeseburger Supreme Contest!

It's time for the first-ever contest on Cheeseburger Supreme. See that photo on the right of Mr. Cheeseburger-Head in a tuxedo? Well, our artist-in-residence (Me) created this lovely photograph. The cheeseburger is mine, but where did I get the inspiration for this graphic, and where did the rest of the photo come from? The first to send in the correct answer will win a one-off t-shirt featuring the aforementioned photo! Notice the clue?
