I have just discovered (I should have thought of looking earlier -- Germans are supposed to be thorough!) that a complete archive of Der Spiegel is available on the Web, and that the article I mentioned ("Fruehling fuer Hitler und Lili Marleen") may be read at
http://wissen.spiegel.de/wissen/dokument/dokument.html?id=14319633&top=SPIEGEL
(That is plain text. A click will get you to a .pdf of the original article, including the pictures, but the latter are reduced to black & white and are rather garish.)

In the same issue, you can also amuse yourself with Reagan's inauguration (including a reproduction of an ad in which during his movie-star days he had praised Van Huysen wrinkle-free shirts), a thorough explication of Rubik's cube, and a no-minced-words review of the "Schwulenkomoedie" Taxi zum Klo.
