It has been established that artists Charles P. Kilgore and Orrin A. White served as US Army camoufleurs in Washington DC during World War I. But it is not commonly known that they were friends of and served in the same camouflage unit as Regionalist painter Grant Wood. Years after the war, in 1933, the three artists exhibited together at Younkers Department Store in Des Moines, for which they were described as having "served in the same camouflage squad during the world war."
A news clipping is included in a series of scrapbooks, put together by Nan Wood (the artist's sister), and is viewable online at the Iowa Digital Library's site for the Figge Art Museum Grant Wood Digital Collection. The source of the news article was not preserved, but it is most likely from the Des Moines Register and Tribune, accompanied by the penciled note "Nov 1933?"
