Color Multiplied in Thousands
These photographs were taken by Werner Kranwetvogel at the “Mass Games” in North Korea. “The effect of displaying huge images is achieved by having a large number of performers, each dressed in a particular color or holding a sheet of colored cardboard above their head. Because of the vast scale of the performance, often with tens of thousands of performers, mass games are performed in stadiums, often accompanied by a background of card-turners occupying the seats on the side opposite the spectators.”
