Sea World is an aquatic amusement park. Founded in California in 1964, Sea World has since grown to have several locations across the States as well as several international locations. The parks were known for their marine life exhibitions, although more recently they have begun to phase out their most popular attraction, Shamu the killer whale. One mascot who also seems to have been lost is Pete The Penguin, a cute little penguin who wears a hat to stay warm. This vintage Sea World shirt from 1988, in great condition, features portrait of Pete The Penguin.
