Accepted into college - celebrating with a cruise

[FirstTimeCruiser]

My husband just found out he was accepted as a transfer student into a certain college and we just happen to be going on a cruise in a few weeks! I'd like to make him a sign for the door, but I can't think of any ideas. Would a DIS-igner be able to help out? The college is Cal Poly Pomona, and their logo is a Bronco. School color is green. His favorite Disney related character is Jack Skellington and we'll be sailing on the Disney Magic. Oh, and husband's name is Matt. Any takers? Thanks so much in advance!
