Compiled and expanded by Nancy Finston, The 20th PID Book revives a rare 1945 commemorative volume created by the 20th Photo Intelligence Detachment of the Ninth Air Force. Rich with original wartime artwork, aerial photographs, maps, reports, cartoons, and personal reflections, this restored edition offers a vivid portrait of a specialized intelligence unit whose analysis shaped the Allied advance across Europe. Drawing on her father Lt. William J. Snodden’s archives, Finston adds historical insight and commentary that preserve the humor, camaraderie, and legacy of a remarkable WWII team. Presented in a collectible landscape-format hardcover, it’s a tribute to a unit whose story deserves to be remembered.
