"Pop" Momand gave the English language the phrase "Keeping up with the Joneses," by using it as the title of the popular comic strip he started in 1916. He started as a sketch artist at the New York World. He drew the strip until 1945, after which he became a portrait painter. For a more complete history see Lambiek.net, also Don Markstein's Toonpedia.
All the time he kept up his figure drawing. These are two pages from a sketchbook, one a study of hands, the other of feet. They are on the Ebay Auction site.
The artistic life must have agreed with him, he lived to be a hundred and one.
