N.C.A. Digest

From MagicPedia

N.C.A. Digest was a Magic Periodical by Charles J. Hagen as the official organ of the National Conjurers Association that began with the August 1920 issue.

It stated it would begin printing quarterly in the Oct/Dec, 1921 issue, which I believe was the last issue.

N.C.A. Recorder followed the Digest and was also edited by Charles J. Hagen. It ran from July 1913 until 1914.
