An avid photographer his entire life, Glenn left behind an expansive archive of his visual craft - tucked away for years at his family's farm outside of Gainesville, Fla. - including the world's only known 3D photographs taken of war-time Vietnam. Joel's widow Judy and son Tom also allowed the use of many of the voice "letters" exchanged during the family's time apart. Seen and heard for the first time, the immersive 3D photographs and voice recordings - along with modern day interviews with the Glenn family and his fellow soldiers in combat - offer a deeply personal, first-hand perspective of one of the most enigmatic times in American history. New 3D technology enables Glenn's photographs to be experienced as never before.
