I have added a page to the Photo Ephemera section of my vintage cameras web site about Ansco's Portrait Magazine, published from 1909 to 1921. Ansco's publication resembles those of Kodak and Sears from the same era, but the Binghamton, New York company slanted it's editorial efforts much more toward a commercial professional audience.
Each issue of Portrait featured a cover shot of a noted portrait photographer and an article inside with a bit of biographical information and a sample of the photographer's work.
Gertrude Käsebier was featured in the July 1912 issue. The sample of her work in the publication is not a memorable example of her capabilities. Alfred Stieglitz included six of her best in the first issue of Camera Work in 1903, but by 1912 he had decided that her efforts to make a living from her work violated his standards of artistic purity. That, however, did not stop Stieglitz from participating as a featured speaker at the Ansco-sponsored photo convention being promoted in the July Portrait issue. In that context the magazine's editors noted:
One of the many features of the Convention will be a talk by Alfred Stieglitz, who, although not a professional photographer is recognized as a leader of pictorial photography.Stieglitz was probably ok with being excluded from the "professional" category, but my guess is that the wording of the announcement still rankled a bit.
