The pictograms were designed by more than 500 primary school students based in Argentina’s capital.

They were instructed to trace a photograph of an athlete in a pose related to his or her sport in one continuous stroke, without lifting their pencils.  

The project is part of the cultural, educational, and sport programme for Buenos Aires 2018 that is said to be bringing the values of Olympism to hundreds of thousands of boys and girls in schools throughout Buenos Aires.

There are 34 pictograms in total with some, such as those for new sports breaking and sport climbing, described as a "big challenge".  

"Our objective for the Buenos Aires 2018 pictograms was to show the essence of our project, and the children and youth from Buenos Aires are the centre of our Games," Buenos Aires 2018 President Gerardo Werthein said.

"The pictograms are a gift from the schoolchildren in Buenos Aires to the young athletes of the world."

The project, directed by the design agency Prójimo, started with dozens of young Argentine athletes doing poses related to their sport in front of the camera and under the supervision of the Argentine sports federations.

Using these pictures, notebooks were made and handed out to more than 500 primary students from both public and private schools.

The four-month process finished at the desks of graphic designers as they looked for common points among the drawings to create the pictograms.

They were then approved by the International Federation of each sport.

Among the young athletes who served as models for the pictograms were Valentina Pisani, Yovela Petrucci and Brenda Romero, representing athletics, badminton and breaking respectively.

The 2018 Summer Youth Olympic Games is due to take place from October 6 to 18.

International Olympic Committee President Thomas Bach visited Buenos Aires in April of last year to check on preparations for the Games.
