A visit to my favorite used bookstore this past weekend turned up this WWII era UK collection, I Couldn’t Help Laughing! (edited by D.B. Wyndham Lewis). This is the “new & enlarged” 1944 edition (cover by Nicolas Bentley). The original edition came out in ’41.
As you can see by the list of contributors shown below right, there are a trio of New Yorker artists represented: Bruce Bairnsfather, Fougasse, and David Langdon.
Excerpt from the book flap:
“It is one of the characteristics of the English to laugh when things go wrong and in moments of strain and crisis. It is the quality above all others which helps to carry them through.”
The Spill A-Z entries for Bairnsfather, Fougasse, and Langdon:

Cyril Kenneth Bird 
Born, London, December 17, 1887. Died, 1965. NYer work: 1 cartoon, March 28, 1925. Known professionally under the name Fougasse, Bird became art editor of Punch in 1937, and assumed the title of editor in 1949. Key book: The Good-Tempered Pencil, A Survey of Modern British and American Humorous Art (Max Reinhardt, 1956).
David Langdon born, London, February 24, 1914. His work is perhaps most identified with Punch, where he contributed from 1937 through 1992, when Punch ceased to publish. He was elected to the Punch Table in 1958. NYer work: 1945 -1973. Key book: Langdon At Large ( Wingate, 1958)
It was lovely to be reminded of David Langdon, whose cartoons I relished in the ’70s when my high school library had a new Punch in every week.
