Explanation:

Jews over the age of six in Germany are required to wear a yellow, six-pointed star with the word "Jude" (German for "Jew") across the front in black, sewn to their outer clothing at all times. Jews are now identifiable on sight in Germany. Systematic deportations of Jews from Germany begin in October. In March 1942, Jews are also required to display the star symbol on their residences.
