On the backs of all cards from the card file of the AJDC Location Service Belsen, the same information is found: AUG 18 1954, which stands for the 18th of August, 1954. ITS employees would often stamp cards with the date on which they were placed in the postwar card file (Nachkriegszeitkartei, Collection 3.1.1.1). Other DP cards from the postwar period also have a stamp on the back and the initials of the responsible employees.
