A yellow Star of David bearing the letter J, which Jews were required to wear visibly on their clothing. On 29 April 1942, the star became compulsory for all Jews from age 6 and up. The star was intended to make the Jews completely stigmatized and excluded. Defiance of the ordinance was especially risky because of the meticulous registration of persons and the requirement to carry proof of identification, which was stamped with a ‘J' for Jews. Jews who were caught without the star risked immediate deportation as criminal offenders.
