What Should Collectors Watch For?
- Nothing can postdate March 1941.

- Signed photographs need comparison with authenticated exemplars.
Loss of U 47
U 47 was lost on or about 7 March 1941 south of Iceland; the cause remains unclear.
Collector’s Note
Prien became a propaganda hero overnight, and printed postcards of him circulated widely. A printed signature on such a card is not an autograph.
