Indonesian 18-year-old Muhamad Farid Husen's entry has been selected following nearly 300 submissions from more than 50 countries.

His design is called "Fireworks of Victory" with a panel of judges, featuring young change-makers, young reporters and International Olympic Committee (IOC) members, selecting him as the winner.

"It is really an honour for me to be a little part of the Youth Olympic Games," said Husen.

"I can't describe how my feeling is, being the designer of the medals which will be worn by all the winners of the Youth Olympics is an honour for me. 

"My dream came true.

"This medal was inspired by fireworks. 

"Fireworks representing the excitement and the glory of the Youth Olympic Games where all nations come together as one to participate and celebrate. 

"Fireworks fly to the sky, giving the reflection of how the young athletes are reaching their dreams."

Husen, who is the youngest-ever winner of the medal competition since its first edition in 2010, will now see his design used on gold, silver and bronze medals in Argentina's capital.

He has been rewarded with a trip to the Buenos Aires 2018 Opening Ceremony while he will also receive his own set of medals and a Samsung tablet.

Aya Medany, an Egyptian member of the IOC's Athletes' Commission, was part of the judging panel.

"Muhamad's design really touched my heart as an athlete," the former modern pentathlete said.

"The most important thing is to celebrate after winning, and it's nothing better than to celebrate with fireworks. 

"It's also amazing to have the winner the same age as the participants in the Youth Olympic Games." 

The Games will run this year between October 6 and 18.
