Koralle was a monthly popular science magazine which appeared in Weimar Republic and then in Nazi Germany between 1925 and 1944.
It was one of the publications started by the leading German company Ullstein Verlag.
The magazine featured advertisements about the novice technical devices such as cameras and cars.
However, Koralle lost its original focus and became a general interest magazine shortly after the Nazi Party seized power in 1933.
[4] In the period between 1926 and 1933 Koralle sold tens of thousands copies, being one the most successful Ullstein titles.
