For some of his more erotic works of art, Emil Ranzenhofer used the following two aliases:
In collaboration with the Marquis von Bayros he used the name Emil Sartori for some eighteen illustrations in the Die Bonbonniere – Galante und artige Sammulung erotischer Phantasien. Die Bonbonniere was published in 1907 by C.W. Stern in Vienna. The first twelve illustrations were by von Bayros.
Six illustrations by Emil Sartori (aka Emil Ranzenhofer) were to accompany the book Ein Roman aus Bernil W. written by James Gunert and published in 1908. Due to their erotic nature, the illustrations were probably issued under separate cover.
Emil Rantzi was the alias he used for about ten illustrations in four volumes of the Das Buch der Tausend Nachte und der einen Nacht series. Four illustrations were in Volume 2, and two each in volumes 4, 5, and 6. Das Buch der Tausend Nachte und der einen Nacht was a limited edition (520) series of eighteen volumes privately printed for subscribers over a period of nine years (1906 - 1915). Although the text was not censored, the illustrations were due to their erotic nature. So, after the first volume, the illustrations were sent in a portfolio under separate cover.
