The Star-Spangled Banner (aka, "The Fort McHenry Flag")
features fifteen stars and fifteen stripes and is flown over Fort
McHenry in Baltimore, Maryland, as it was in 1814 when Francis
Scott Key composed the U.S. National Anthem.
The 15 star US flag was used from 1795 - 1818. The two stars
that were added were for Kentucky and Vermont.
