Paper Salvage: Germany 1943

I've not read much about paper shortages in Germany during the Second World War, but there's every reason to expect that the production of paper was a serious concern -- certainly by the end of the war there was a marked deterioration in paper used in cheap publishing, with many books of this period printed on thin, grey, brittle stock. This poster, for a paper salvage drive in April 1943, certainly confirms that it was a serious issue for the Nazi government, and for that matter, that paper drives in all countries were targetted at children. It does seem unusual that the children depicted here are in casual clothes rather than Hitler Youth uniforms. It's also worth pointing out that while newspapers are evidently the main focus, that the likely looking lad in the front does have a book tucked under his arm -- although book pulping represented a significant proportion of paper pulping, it is uncommon to see it directly alluded to in advertising.
