Franké did quite a lot of work for Robert Collier’s How 7 through its limited existence. Collier’s next publication, Mind, Inc. was a successor of sorts. Based on the small number of issues available, Mind, Inc. contained little to no art.
What we did find in the June 1929 issue was an advertisement for Man and His Powers by Richard Lynch. It contains a portrait of the author which I’ve reconstructed a bit.
This same image was also used in single-page advertisements for Work and Supply, another of Lynch’s books. This ad appeared in the July 1929 and August 1930 issues.
