Wimbledon champion Billie Jean King checks the muscle on her nemesis, Bobby Riggs, in New York, July 11, 1973. King and Riggs announced they will meet in a $100,000 tennis grudge match like the one in which Riggs bested Margaret Court earlier this year. Time and place is yet to be announced. Mrs. King is 26 years younger than Riggs. (Photo by Anthony Camerano/AP Photo)
