The April 11, 1925 issue of The New Yorker is a bit of a hodgepodge, which is true of most of the early issues that are pretty spotty in terms of content. Much of the writing is heavily embellished with cheeky asides, wordplay and the like.
I should note at this point that although I am reading every page of every issue, including ads, what I represent here is what catches my eye and appeals to my particular sensibilities. It is by no means a comprehensive survey. Nevertheless, I hope that my selections give you a good sense of the content of the magazine, and the context of the times and places where the action occurs.

“Talk of Town” opened with rumors of a baby at the Coolidge White House, which proved unfounded. There was also a brief item noting that silent film star Gloria Swanson (who will be prominent in the early issues) was back in the states with her husband, the Marquis de la Falaise de la Coudraie (the marriage ended in 1931, when the Marquis married actress Constance Bennett).
“Talk” also mentioned that a long anticipated boxing match between Harry Wills and Jack Dempsey had hit a snag with the state athletic commissioner.

Boxing historians consider Wills one of the most egregious victims of the “color line” drawn by white heavyweight champions. Wills fought for more than twenty years (1911–1932), was ranked a No. 1 challenger for the throne, but was denied the opportunity to vie for the title. He spent six years (1920–1926) trying to land a title fight with Dempsey, who was willing to fight Wills but backed out when he did not receive a $100,000 guarantee from a boxing promoter. Wills filed suit for breach of contract, leading the athletic commissioner to bar Dempsey from competing in the state (Dempsey would later lose in points to Gene Tunney in a Philadelphia bout).

“Talk” offered a brief item on a “new religion” making the rounds, run by A. E. Orage. It noted that he was a disciple of Gurdjieff (and I should add both are offspring of Madame Blatavsky’s Theosophical Society) who “took New York by storm” the previous year. “Talk” said Orage offered classes “in which he intensifies the soul for $10 a month.”

The issue also marked the first appearance of darkly-themed woodcuts on various Victorian subjects by John Held Jr. He is perhaps even more famous for his variety of illustrations throughout the 1920s that captured the flapper era, and no doubt why he is still known for his work today.

“Profile” featured famed birth control rights advocate Margaret Sanger in a piece titled “The Child Who Was Mother to a Woman.” Although “Profile” mentioned her great cause, it was largely focused on her defiance of authority, her championing of free speech (which she inherited from her father, a carver of tombstones), and of her ability as a small, timid woman to overcome the fear of speaking in public.
In this issue we are treated to Miguel Covarrubias drawings of contemporary celebrities:

The “Motion Pictures” section noted the following: “Texas Guinan, Hard Hearted Hannah and the gals of the El Fey Club (recently padlocked, see my entry “A Dry Manhattan”) moved over to the Famous Players Astoria studios the other day to lend the right color to Allan Dwan’s production, “Night Life in New York.”…unless the censors cut the scenes, Kansas, Iowa and other inland points can glimpse how Manhattan spends its evenings when it isn’t trying to get Havana or Oakland on the radio.”
Famous Players Astoria studios (originally Famous Players-Lasky) was located near the Broadway theatre district. Two Marx Brothers films–The Cocoanuts (1929) and Animal Crackers (1930)–were filmed there. Although Lasky’s Paramount moved the studio operations to California in 1932, the Astoria location continued to thrive, used first by the U.S. Army (beginning in 1942) to make indoctrination films and later by other studios and networks to make everything from music videos, to films (Goodfellas) to television programs (Sesame Street).

The “Motion Pictures” section also mentioned that German director F. W. Murnau (perhaps most famous today for the original 1922 Nosferatu) was coming over to direct. The New Yorker observed that “he the most distinguished screen newcomer since Ernst Lubitsch came over.”
German actors and directors featured prominently in early New Yorker reviews. They were drawn to America by artistic opportunity, however. Later actors and directors (and other artists) would come over to flee Nazi persecution.
But then again, readers of the April 11, 1925 issue don’t know that yet.
