In order for the DP identity card to be valid, a passport picture had to be attached and the issue date (date d’émission) had to be entered. The head of the DP department (Section des Personnes Déplacées) signed the identity card. The stamps came from various officials: individual UNRRA teams stamped them, as did the responsible departments of the respective regional military institutions, such as the Gouvernement Militaire du Wurtemberg and the Section des Personnes Déplacées of the Lörrach military government.
