I saw the following picture in August 2023:
artist: William Cotton (1880-1958) for The New Yorker cover August 12, 1944
They are 'outraged' by the pictures hanging in a barrack.
Now see the picture below:
artist: Ned Hilton (1904- 1967) for the New Yorker
This time it's a school dormitory and a good explanation for why the picture is there...
