I recently subscribed to The New Yorker online so that I could become dangerously addicted to their massive archive of past issues. Here are a few of my favorite covers by Steig, who created thousands of covers and cartoons for the magazine beginning in 1930. Plus... a book I found on Etsy! There's a wonderful postscript to his life here.
This is my favorite: June 18, 1960 New Yorker | William Steig
May 9, 1953 New Yorker | William Steig
