Greece is of course the birthplace of the Olympic Games.  These pins were issued by NBC each month before the games starting 12 months before the start of the 2004 Athens summer games.  

Each pin depicts an athlete from a summer Olympic event and each is mounted on a spring which allows the pins to move.  This set of pins is unique and rare to find as a complete set together.  The pins came brand new and in the wrapper so in excellent condition.  Please see pictures for reference and message with any questions.
