It may look like a slightly sinister sight, but these drones weaving headless mannequins through the skyscrapers of Sao Paulo are the latest weapon in Black Friday advertising.
Brazilian shirt store Camisaria Colombo came up with the idea of flying the drones around the city's corporate district to bring its special deals to "businessmen who don't have time to leave the office."
The mannequins wore threads from The Flying Collection, including discounted polos and tailored shirts.
The stunt is the latest incident of drones taking over the mainstream retail scene. Earlier this fall TGI Fridays restaurants in Britain unveiled special "mistletoe" drones to encourage diners to lock lips over the festive season.
