Some context: Norman Percevel Rockwell (February 3, 1894 - November 8, 1978) was a 20th-century American author, painter and illustrator. His works have a broad popular appeal in the United States for their reflection of American culture. Rockwell is most famous for the cover illustrations of everyday life he created for The Saturday Evening Post magazine over nearly five decades. Among the best-known of Rockwell's works are the Willie Gillis series, Rosie the Riveter, The Problem
Rockwell's family moved to New Rochelle, New York, when Norman was 21 years old. They shared a studio with the cartoonist Clyde Forsythe, who worked for The Saturday Evening Post. With Forsythe's help, Rockwell submitted his first successful cover painting to the Post in 1916, Mother's Day Off (published on May 20). He followed that success with Circus Barker and Strongman (published on June 3), Gramps at the Plate (August 5), Redhead Loves Hatty Perkins (September 16), People in a Theatre Balcony (October 14), and Man Playing Santa (December 9). Rockwell was published eight times on the Post cover within the first year. Ultimately, Rockwell published 323 original covers for The Saturday Evening Post over 47 years. His Sharp Harmony appeared on the cover of the issue dated September 26, 1936; it depicts a barber and three clients, enjoying an a cappella song. The image was adopted by SPEBSQSA in its promotion of the art.  Rockwell's success on the cover of the Post led to covers for other magazines of the day, most notably the Literary Digest, the Country Gentleman, Leslie's Weekly, Judge, Peoples Popular Monthly and Life magazine.  When Rockwell's tenure began with The Saturday Evening Post in 1916, he left his salaried position at Boys' Life, but continued to include scouts in Post cover images and the monthly magazine of the American Red Cross. He resumed work with the Boy Scouts of America in 1926 with production of his first of fifty-one original illustrations for the official Boy Scouts of America annual calendar, which still may be seen in the Norman Rockwell Art Gallery at the National Scouting Museum in the city of Irving near Dallas, Texas.  During World War I, he tried to enlist into the U.S. Navy but was refused entry because, at 140 pounds (64 kg), he was eight pounds underweight for someone 6 feet (1.8 m) tall. To compensate, he spent one night gorging himself on bananas, liquids and doughnuts, and weighed enough to enlist the next day. He was given the role of a military artist, however, and did not see any action during his tour of duty.

Some context: John Griffith "Jack" London (born John Griffith Chaney; January 12, 1876 - November 22, 1916) was an American novelist, journalist, and social activist. A pioneer in the world of commercial magazine fiction, he was one of the first writers to become a worldwide celebrity and earn a large fortune from writing. He was also an innovator in the genre that would later become known as science fiction.
London wrote from a socialist viewpoint, which is evident in his novel The Iron Heel. Neither a theorist nor an intellectual socialist, London's socialism grew out of his life experience. As London explained in his essay, "How I Became a Socialist", his views were influenced by his experience with people at the bottom of the social pit. His optimism and individualism faded, and he vowed never to do more hard physical work than necessary. He wrote that his individualism was hammered out of him, and he was politically reborn. He often closed his letters "Yours for the Revolution."  London joined the Socialist Labor Party in April 1896. In the same year, the San Francisco Chronicle published a story about the twenty-year-old London giving nightly speeches in Oakland's City Hall Park, an activity he was arrested for a year later. In 1901, he left the Socialist Labor Party and joined the new Socialist Party of America. He ran unsuccessfully as the high-profile Socialist candidate for mayor of Oakland in 1901 (receiving 245 votes) and 1905 (improving to 981 votes), toured the country lecturing on socialism in 1906, and published two collections of essays about socialism: The War of the Classes (1905) and Revolution, and other Essays (1906).  Stasz notes that "London regarded the Wobblies as a welcome addition to the Socialist cause, although he never joined them in going so far as to recommend sabotage." Stasz mentions a personal meeting between London and Big Bill Haywood in 1912.  In his late (1913) book The Cruise of the Snark, London writes about appeals to him for membership of the Snark's crew from office workers and other "toilers" who longed for escape from the cities, and of being cheated by workmen.  In his Glen Ellen ranch years, London felt some ambivalence toward socialism and complained about the "inefficient Italian labourers" in his employ. In 1916, he resigned from the Glen Ellen chapter of the Socialist Party, but stated emphatically he did so "because of its lack of fire and fight, and its loss of emphasis on the class struggle." In an unflattering portrait of London's ranch days, California cultural historian Kevin Starr refers to this period as "post-socialist" and says "... by 1911 ... London was more bored by the class struggle than he cared to admit."
