Seven Circles (all 5 Volumes) by Walter Gibson

Seven Circles was the official publication of the International Magic Circle (IMC). Editor-in-chief was Walter B. Gibson. In his first editorial Gibson wrote:

This magazine has a double purpose, as a perusal of its pages will show. First, it is a desire to give magicians a worth-while, readable publication, filled with items of value and interest. Second, it is definitely the magazine of a new organization - The International Magic Circle.

It is the editor's duty to produce a magazine that will be recognized as the best of all periodicals pertaining to the mystic art. There is only one basis of true excellence. That is quality. Good, useful material; clear, understandable illustrations: interesting, readable articles and notations are the real standard.
