On April 4, 2002, the Postal Service released a commemorative set of postal stamps honoring the 50 states. The set was called "Greetings From America." Now, with this nifty cardstock collector's kit, kids can store those stamps inside small acetate pockets for safekeeping. Along the way, they'll learn about stamp collecting techniques (parts of a stamp, handling, grading, etc.) and important nuggets of United States state trivia.
