Of the creative cycle of the limited art prints of the Jewish and Christian art works by Dr. Elias Rubenstein, there are six designs each available at the shop. Sold out designs are replaced by new illustrations. The number six corresponds to the six working days, representing the period of activity. The seventh day constitutes the day of rest, referred to in the Bible as Shabath (Sabbat, Shabbath). In the Kabbalah and Hermeticism, these two numbers have also a profound meaning.
