German poster for the French. It confused me at first glance due to the art/language clash. (" While Working In Germany, You Will Be The Ambassador Of French Quality 1943 - poster from Vichy France by Raoul Eric Castel")
Postcard, language is Italian. Clearly WWII but I can't work it out. I assume the caricature in the middle is supposed to be "England", but they're a bit off - it looks like George IV (lol) not George VI!
