Women's Army Corps Song Book. I've written about this book before and said I wanted to scan the pictures, but here's a website where someone has done that. You can get a sense of how charming the line drawings are, though they are reduced in size here and don't look as crisp as in the actual book. My copy, which was my mother's, is in better condition that the one scanned here. There's only a 17 on that page's hitometer, so go over and hit that page, please. You can click on the links and get to song lyrics, like this from the WAC version of "We're In the Army Now":

We'll stand Reveille scantilly clad,
Wearing cotton is the latest fad,
We don't care, we'll show them how
We're in the Army now.

Who would have thought the words "scantilly clad" (misspelling in original) would appear in an official government military song? And to think that wearing cotton could have been perceived as a hardship!
