This postcard was sent from Copenhagen, Denmark, by Arnold Cohn to his brother Simon. Both were veterans of the German army and fought in World War I. Simon resided in the Theresienstadt ghetto, but Arnold was fortunate enough to get out of Germany and escape to Copenhagen. Arnold sent a return-receipt postcard to his brother; when Simon received it, he was to sign the pink card and send it back to Arnold, letting his brother know he was still alive. Unfortunately the card was returned in its entirely; Simon apparently was deported to the East.

This postal card was cancelled in Copenhagen and stamped Zurück. Unbekannt,  meaning “Return. Recipient unknown.” The rest of the stamp reads “By the Committee for the Jewish Problem in Bohemia and Moravia.” Note that the pink return-receipt postcard is still attached to Arnold’s card.
