Arthur Ashe Kids' Day
At the 2005 event, the United States Postal Service unveiled and issued the Arthur Ashe Commemorative Postal Stamp in the presence of the Ashe family. The 2011 event originally scheduled for August 27, 2011 was cancelled in the wake of the forthcoming Hurricane Irene. This marked the first time the event was cancelled in advance. Participants at the Arthur Ashe Kids Day have an opportunity to play and/or watch numerous tennis matches before and after the main event at Arthur Ashe Stadium at the USTA Center. The main event at the stadium consists of a concert  and tennis matches. As people enter the stadium, they are handed hats to commemorate the event. Tennis greats that have appeared annually at Arthur Ashe Kids Day include Venus and Serena Williams, Roger Federer, Rafael Nadal, Andre Agassi, Andy Roddick, Novak Djokovic, Kim Clijsters, and Anna Kournikova, who play to entertain the children and families and to raise money for charity.
