Brazilian paints massive Olympic mural

Perched atop a cherry-picker truck several stories high, Brazilian graffiti artist Eduardo Kobra sprays puffs of paint on a sprawling mural in the colors of the Olympic rings.

With three weeks to go to the Summer Games in Rio de Janeiro, Kobra and his assistants are racing to put the finishing touches on the 3,000-square-meter painting that graces a wall in the city's newly overhauled port district.

The mural depicts five indigenous faces representing the continents of the world, awash in the blue, yellow, black, green and red of the Olympics.
