Vatican City ~ FlagThe Vatican City flag was adopted on June 7, 1929. The colors of gold and silvery-white are the colors of the keys of St. Peter's (the keys to heaven). The emblem centered on the white panel features those keys supporting the papal crown. The keys are tied together by a reddish rope. The flag, like that of Switzerland, is perfectly square.

In this surprising and hilarious talk about vexillology -- the study of flags -- Mars reveals the five basic principles of flag design and shows why he believes they can be applied to just about anything.
