Circa 7 years ago I acquired copies of enlistment, propaganda, sensitive, campaign, first world war posters from LAC, Library Archives Canada. The collection consists of over 2000 posters from Canada, Briton, France, American, and French Canadian, with other languages depending on the regional area in Canada. 6 years ago around 15 Canadian FWW posters were found on line until I posted over 50, not counting Second World War Posters.
Since I have over 1500, I’ll post several categorise blogs as fallows:-
