The U.S. flag was formally adopted by the Second Continental Congress on June 14, 1777. While the first presidential proclamation celebrating flag day was not signed until 1916 and the first congressional legislation wasn&amp;#8217;t passed until 1949, Americans still celebrated the birth of our nation&amp;#8217;s flag on June 14. In this 1901 cartoon by Clifford Berryman Uncle Sam is celebrating flag day while carrying a large flag and small boy dressed as a sailor.
