In June 1944, a secret U.S. Army unit went into action in Normandy. The weapons they deployed were decidedly unusual: hundreds of inflatable tanks and a one-of-a-kind collection of sound effects records. Their mission was to use bluff, deception, and trickery to save lives. Many were artists, some of who would become famous, including a budding fashion designer named Bill Blass. They painted and sketched their way across Europe, creating a unique visual record of their journey. The story of what these men accomplished was hushed up by the Pentagon for more than forty years.
