Anna Kournikova in a sports bra ad

Russian tennis player Anna Kournikova poses in an ad for Shock Absorber sports bras, circa 2000. Anna Kournikova was born in 1981, so she would have been about 19 years old when this ad was shot. Kournikova was at the peak of her celebrity at the time; she was named the world's most-searched athlete by the Lycos 50 that year. She retired from the main professional tennis circuit in 2001, in part due to back injuries.
