This stamp means that there is a CM/1 folder for the DP in the Arolsen Archives. The CM/1 folders were sent to the International Tracing Service from 1953. They were used by the IRO to collect documents about people applying for DP status. It is therefore always worth looking in the collections of the IRO Care and Maintenance program (Collection 3.2.1 in the Arolsen Archives). The CM/1 folder for Krystyna Wuccen – like all other CM/1 folders – can be viewed in the online archive of the Arolsen Archives.
