At The New Yorker’s Midtown offices, a wall of covers arranged in chronological order shows a distinct change in tone. Today, the magazine’s covers, which have been drawn or painted by artists each week since its founding in 1925, frequently reflect, or subvert, the news.

The turning point is around Sept. 11, 2001, Mr. Remnick said, when The New Yorker ran a black cover with a black silhouette of the twin towers, by the Pulitzer Prize-winning artist Art Spiegelman, who has long collaborated with his wife and the magazine’s art editor, Françoise Mouly.

A great article about magazine cover design, illustration, and process.
