On the back of the commemorative medallion is the torch symbolizing light, unity and friendship, and the number of the Olympic Games. In addition to medals, the organizing committee of the Olympic Games will also issue Olympic certificates to each contestant. Take the 23rd Olympic Games as an example. The certificate is 38x38, wrapped in a big envelope. The certificate says: xxx, thank you and reward you for your contribution to 1984 Los Angeles Olympic Games. In the middle of the certificate is the Olympic emblem. The following are the signatures of the President of the International Olympic Committee and the President of the Olympic Organizing Committee.
According to the provisions of the Olympic Charter, medals or certificates awarded at the Winter Olympics must be different from those awarded at the Summer Olympics. Commemorative medals and certificates cannot be issued to members of delegations who have withdrawn from the Olympic Games. If an athlete participating in the Olympic Games is disqualified, his medals and certificates must be returned to the International Olympic Committee. In addition, the design of the commemorative medallion is the same as that of the medal, and its copyright belongs to the International Olympic Committee. If the host country requests the transfer of copyright, the organizing committee of the Olympic Games must draft the necessary documents in writing and ask the IOC to sign them.
