Before World War II, a Jewish craftsman made a living making ironware in Berlin. After World War II began, the craftsman knew that he and his wife would be in disaster, so he fired a pair of photo frames with his own hands, and engraved "Für immer" on the two photo frames before they were divided. They put in their own photos as a symbol of their longing and recognition in the future. In 1946, Hitler purged the Jews in Berlin, and the craftsmen were separated from their wives in a concentration camp. Later, he died of illness in the camp and was never able to see his wife before his death. After World War II, the pair of photo frames passed through the hands of an Austrian businessman. The businessman re-polished the picture frame, but still retained the original "Für immer" notch, and set it with crystal, which was circulated on the market.
