Font used on US VD Propaganda Poster, circa 1940

Hi, I've read the guidelines, but I apologize in advance if I'm doing some incorrectly. I'm trying to figure out the font used on [[http://upload.wikimedia.org/wikipedia/commons/2/28/SheMayLookCleanBut.jpg|this poster]]. Near as I can tell, it's the same font for all the text, save for "VDgraphic - 9" in the bottom left corner, which isn't important.

I've tried to identify this font myself, and I've tried using WhatTheFont! and Identifont, but, to no avail. The guide here also linked me to Type Navigator at typenav.fontshop.com, but that appears to be down.
