In the spring of 2008, the U.S. Postal Service® introduced Set 1 of Flags of Our Nation, a 3-year, multi-stamp series, featuring the Stars and Stripes, the 50 state flags, five territorial flags and the District of Columbia flag.
Set 2 will be issued in the fall and will feature flags from the District of Columbia through Kansas. The same process will be repeated in 2009 and 2010, for a total of 60 stamp designs. Four of the six groups of 10 will include a Stars and Stripes stamp.
