This is a WW1 recruitment poster from Canada.

The ideolgical perspective presented is that anyone who enlists and fights in the war has the chance to become a "new name in Canadian history."

The four words on the flag are all sites of WW1 battles that Canada took part in (mostly supporting Britain and France).  Many have since had war memorials dedicated strictly to the fallen Canadians, suggesting that the Canadian men who fought and died in these battles are national heroes.

Nationalism, therefore, is portrayed through the bandwagon technique.  "More are coming, will you be there?" suggests that if you aren't, you don't love your country.
