This Bar Mitzvah greeting features a funny cartoon Jewish boy, Jewish Rabbi wishing you a happy Bar Mitzvahs.
The jewish boy has its Kippah ( hech cap or yarmulke) traditionally worn at all times by observant Jewish men.
The rabbi is dressed in formal orthodox jewish clothes and hat. He has a long white beard and Peyes Sidecurls, worn by some religious jews.
According to Jewish law, when Jewish children reach 13 years old for boys and 12 years old for girls they become responsible for their actions, and "become a Bar or Bat Mitzvah" (Daughter (Bat) or Son (Bar) of the commandments) In Orthodox Jewish observance, the occasion of becoming a Bar Mitzvah involves the young man being called to read the Torah, a Haphtarah portion, or both at a Shabbat or other service.
With this Postcard he will surely have a "Happy Bar Mitzvah"!
