About the United States of America Flag (source from Wikipedia)
The national flag of the United States of America (the American flag) consists of thirteen equal horizontal stripes of red (top and bottom) alternating with white, with a blue rectangle in the canton (referred to specifically as the “union”) bearing fifty small, white, five-pointed stars arranged in nine offset horizontal rows of six stars (top and bottom) alternating with rows of five stars. The fifty stars on the flag represent the 50 states and the 13 stripes represent the original thirteen colonies that rebelled against the British monarchy and became the first states in the Union. Nicknames for the flag include the Stars and Stripes, Old Glory, and The Star-Spangled Banner (also the name of the national anthem).
