Brazilian street artist Eduardo Kobra (known in the art world as Kobra) has his eye on the prize: he wants to break the Guinness World Record for the largest mural.
And where else to break a world record but Rio? Inspired by the five Olympic rings, his new artwork shows five indigenous men and women from each continent. It covers a whopping 3,000 square metres, and is 190 metres long.
The indigenous groups represented are the Mursi from Ethiopia, the Kayin from Thailand, the Supi from Europe, the Huli from Papua New Guinea, and the Tapajos from the Americas.
It's called Etnias, meaning "Ethnicities" in English, and can be found in the port area of the city, which has recently been rejuvenated.
The mural forms part of Rio's Olympic Boulevard, which is a three-kilometre stretch dedicated to celebrating the Games, with food trucks, screens, fireworks and more.
In an interview with Rio 2016´s official website, Kobra said: "This is the first time I have worked with ethnic people. We've all got the same origins so we have to get along, not only during the Olympic Games but always. We should always stand for world peace.
"We're living through a very confusing time with a lot of conflict. I wanted to show that everyone is united, we are all connected."
Brazilian native Kobra is known for his colourful and large-scale murals all over the world, with a signature geometric pattern.
As a youth he was arrested several times for vandalism, but one judge was so taken by his work that he sentenced Kobra to paint a mural on the police station wall.
"Everything I've learned, I learned in the streets," he said.
Guinness judges will inspect the piece in a few weeks' time, and it's well on track to being a record-breaker.
