In the CM/1 folder for Helena Baranowska and her family, ITS employees placed the applicant’s DP identity card and DP 2 card. The stamp “CM 1 - ITS 1.1.1953” reveals that the cards had first been placed in the postwar card file. After her CM/1 folder arrived in Arolsen, ITS employees stamped a reference to it on the cards filed there. Then, if an inquiry was received, the employees could quickly see that there was other information about Helena Baranowska in the collections of CM/1 folders. It is not clear when the cards were placed in the CM/1 folder itself.
