Conjurers' Monthly Magazine

From MagicPedia

Conjurers' Monthly Magazine was a Magic Periodical by Harry Houdini that only ran for one year from September 1906 until August 1907 as a competitor to the Sphinx.

The magazine touted Houdini's importance to the world of magic, gossip about magicians he did not like and criticism of his imitators.

The series, "Unknown Facts concerning Robert-Houdin" and "Robert-Houdin's Place in the History of Magic", ran for twelve issues which later became a book,The Unmasking of Robert-Houdin.
