Hitler at 50: Rare color photos of a despot’s birthday

The automobile engineer and designer Ferdinand Porsche (in suit) presents Hitler with a convertible Volkswagen for Hitler's 50th birthday, Berlin, Germany, April 20, 1939. "Hitler loved to have his driver tear along at 80 mph," LIFE magazine once noted, "until 1939 when he turned superstitious about accidents and made 35 mph the limit."

Banners hang from buildings in honor of Adolf Hitler's 50th birthday, Berlin, April 20, 1939. The words on the banner, Wir danken dir ("We thank you"), reference a famous Bach cantata, Wir danken dir, Gott, wir danken dir ("We thank you, God, we thank you"), but are obviously addressed to Hitler.
