Prisioneiros uniformizados, marcados com distintivos triangulares, são reunidos pela guarda nazista no campo de concentração de Sachenhausen. A cor de cada triângulo indicava se o prisioneiro era um "inimigo político", um "criminoso comum", um "emigrante", uma "Testemunha de Jehová", um "anti-social", um "homosexual", ou um "cigano". Foto tirada em Sachsenhausen, Alemanha, 1938.
