Norman Rockwell's Willie Gillis character debuts on the cover of The Saturday Evening Post.

Willie Gillis, Jr. (more commonly simply Willie Gillis) is a fictional character created by Norman Rockwell for a series of World War II paintings that appeared on the covers of 11 issues of The Saturday Evening Post between 1941 and 1946. Gillis was an everyman with the rank of private whose career was tracked on the cover of the Post from induction through discharge without being depicted in battle. He and his girlfriend were modeled by two of Rockwell's acquaintances.Gillis was not exclusively used on Post covers, but the Willie Gillis series of covers was a hallmark of Rockwell's wartime work. Rockwell was in his prime, and the Post was at the peak of its popularity with a subscribership of 4 million, and many of these subscribers believed that Gillis was a real person. Rockwell's wartime art contributed to the success of the wartime bond sales efforts, including Willie Gillis, the Four Freedoms, and Rosie the Riveter.The Gillis series has been included in two major Rockwell tours since 1999. It toured as part of a Rockwell Post cover art retrospective from 1999 to 2002, and as part of a 1940s World War II Rockwell art exhibition from 2006 to 2010.

Norman Percevel Rockwell (February 3, 1894 – November 8, 1978) was an American 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 We All Live With, Saying Grace, and the Four Freedoms series. He is also noted for his 64-year relationship with the Boy Scouts of America (BSA), during which he produced covers for their publication Boys' Life, calendars, and other illustrations. These works include popular images that reflect the Scout Oath and Scout Law such as The Scoutmaster, A Scout Is Reverent and A Guiding Hand, among many others.

Rockwell was a prolific artist, producing more than 4,000 original works in his lifetime. Most of his surviving works are in public collections. Rockwell was also commissioned to illustrate more than 40 books, including Tom Sawyer and Huckleberry Finn as well as painting the portraits for Presidents Eisenhower, Kennedy, Johnson, and Nixon, as well as those of foreign figures, including Gamal Abdel Nasser and Jawaharlal Nehru. His portrait subjects included Judy Garland. One of his last portraits was of Colonel Sanders in 1973. His annual contributions for the Boy Scouts calendars between 1925 and 1976 (Rockwell was a 1939 recipient of the Silver Buffalo Award, the highest adult award given by the Boy Scouts of America), were only slightly overshadowed by his most popular of calendar works: the "Four Seasons" illustrations for Brown & Bigelow that were published for 17 years beginning in 1947 and reproduced in various styles and sizes since 1964. He created artwork for advertisements for Coca-Cola, Jell-O, General Motors, Scott Tissue, and other companies. Illustrations for booklets, catalogs, posters (particularly movie promotions), sheet music, stamps, playing cards, and murals (including "Yankee Doodle Dandy" and "God Bless the Hills", which was completed in 1936 for the Nassau Inn in Princeton, New Jersey) rounded out Rockwell's œuvre as an illustrator.

Rockwell's work was dismissed by serious art critics in his lifetime. Many of his works appear overly sweet in the opinion of modern critics, especially the Saturday Evening Post covers, which tend toward idealistic or sentimentalized portrayals of American life. This has led to the often deprecatory adjective "Rockwellesque". Consequently, Rockwell is not considered a "serious painter" by some contemporary artists, who regard his work as bourgeois and kitsch. Writer Vladimir Nabokov stated that Rockwell's brilliant technique was put to "banal" use, and wrote in his novel Pnin: "That Dalí is really Norman Rockwell's twin brother kidnaped by gypsies in babyhood." He is called an "illustrator" instead of an artist by some critics, a designation he did not mind, as that was what he called himself.In his later years, however, Rockwell began receiving more attention as a painter when he chose more serious subjects such as the series on racism for Look magazine. One example of this more serious work is The Problem We All Live With, which dealt with the issue of school racial integration. The painting depicts a young black girl, Ruby Bridges, flanked by white federal marshals, walking to school past a wall defaced by racist graffiti. This 1964 painting was displayed in the White House when Bridges met with President Barack Obama in 2011.
