Walking the Berkshires has a neat analysis of a WWI photograph that purportedly shows a Canadian soldier thumbing his nose as "a gesture expressing his contempt for the Germans."
I wonder if this is an accurate description of what the camera actually captured. Is that soldier thumbing his nose or grimacing at the point of impact? Is anyone holding that rifle, or did he just drop it? And was "cocking a snoot" a standard gesture of contempt utilized by Canadians in 1917 as the American Heritage editors suggest?
