Winterhilfswerk donation can for Duisburg.
The coolest thing about this is the little NSV lock twisted on to the latch.
Much like our Salvation Army bell ringers, people rattled these cans to elicit donations for soldiers on the front line. Once you made a donation, they gave you a donation pin/tinnie.
The Gau Essen was an administrative division of Nazi Germany from 1933 to 1945 in the northern parts of the Prussian Rhine Province.
The paper tag says, 'hilfe für die stadt Duisburg' 'Help for the city of Duisburg'
