The fact that Italian Carlo Malinverno had to perform forced labor at Leuna-Werke AG is not evident from his company personnel card. For this reason, ITS staff stamped the company name on the printout. The date (March 1992/3.92) indicates when the document was cataloged at ITS, the predecessor institution of the Arolsen Archives. There could sometimes be an interval of several years between scanning and cataloging. Date stamps are usually found on the back of documents.
