Jacob Frank (יעקב פרנק Ya'akov Frank, Jakob Frank) (1726-1791) - a Jewish merchant who claimed to be the Jewish messiah. His followers broke away from Judaism and created a new religion known as the Frankists, which was a quasi-Jewish, quasi-Christian religion.
The two-dimensional work of art depicted in this image is in the public domain worldwide due to the date of death of its author (if it is was published outside of the U.S. and the author has been dead for over 70 years), or due to its date of publication (if it was first made public in the U.S. before 1923). Therefore this photographical reproduction is also in the public domain, at least in the United States (see Bridgeman Art Library v. Corel Corp.), in Germany, and in many other countries.
