The collection, held at the COB headquarters, includes a piece of Italo Ferreira's broken board from the surfing final, swimmer Bruno Fratus' cap and goggles in the 50 metres freestyle final, skater Rayssa Leal’s cap and the number of Isaquias Queiroz's canoe sprint boat.

Tennis and volleyball balls signed by Brazilian medallists at the Games are also included in the display.

Gymnast Rebeca Andrade, who won gold and silver at Tokyo 2020, was the guest of honour at the launch and was thrilled to see one of her training suits used at the Olympics on display.

The 22-year-old, who was recently crowned world champion, was welcomed by COB President Paulo Wanderley and Manoela Penna, director of communication and marketing for the organisation.

"Rebeca's presence at the opening of this exhibition at our headquarters is a gift," said Wanderley. 

"This BOC initiative, through our culture and Olympic values department, is unprecedented.

"Bringing the objects of athletes who competed in the last Olympic Games is very gratifying and more than fair for all they achieved in Tokyo.

"Preserving the memory of national sport is one of the main missions of the Brazil Olympic Committee."

Brazil achieved 21 medals at Tokyo 2020 with golds coming from surfer Ferreira, gymnast Andrade, sailors Martine Grael and Kahena Kunze, swimmer Ana Marcela Cunha, canoeist Queiroz, boxer Hebert Conceição and the men’s football team.

The exhibition also features the Olympic Torch and 25 other items from the COB´s memorabilia collection, such as mascots, pins and medals related to Tokyo 2020.

The COB claims to have more than 8,000 pieces from previous Games, including torches, medals, mascots and other objects of Olympic memorabilia.

"The exhibition we open today is a small demonstration of this rich collection of COB," added Penna.

"With it, we want to portray the entire construction of our country's Olympic history."
