Everyone gets into to it
More printed material was produced in 1943 then any other year during WWII
Some American publications "updated" their format during the 1940's to have a more modern look. Saturday Evening Post, with heavy emphasis on illustration from it's early days also changed during the war years to reflect this cleaner look.
The Norman Rockwell appeal - He was "main stream American" with his idealistic illustrations depicted happy middle class America. Just what everyone wanted to be but was a stark contrast to reality. This down-home approach is why Rockwell's illustrations were so widely praised. Even though Rockwell has been criticized for portraying “conspicuous abundance in a hungry world, the 4 Freedoms Series (1943) achieved an iconic presence” Rockwell transformed President Roosevelt’s positive ideals into the reality of everyday life. The printing of the presidents speech and showing these four important pieces of wartime artwork in a somewhat non-political venue demonstrates how the US Government reached far into the home life of Americans with soft and positive influences to “keep them going”.
Wikipedia,, "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 book Pnin: 'That Dalí is really Norman Rockwell's twin brother kidnapped 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."
