This very attractive poster was created for the Olympic Games in Atlanta in 1996 by the well-known contemporary artist Datian.
From one on-line resource: "To commemorate the Year of the Horse in 1990, Datian painted the exquisite Horses series. It garnered acclaim and was eventually selected by the U.S. Olympic Organizing Committee as the basis for the 1992 U.S. Olympic Equestrian Team poster. He earned yet another artist appointment from the 1996 U.S. Olympic Committee. A number of his paintings and sculptures remain an integral part of the Olympic Games Museum."
