Yardley ran this series of wartime adverts over 1942/3. Each shows a woman engaged in "war work" - Wren, factory girl, nurse - and a patriotic message encouraging women to "work hard and let no weariness appear". The superficial read of course is that a woman’s duty above all is to be decorative — but, if you look at it a bit deeper, what intrigues me about this campaign is the focus on a specifically feminine strength.
