WWI - Propaganda postcard - The German Kaiser's dream bubbles are popping before his eyes. By this point however (late 1914), this rosy picture of futile German successes bursting was still a little premature as the war entered stalemate along the Western front. The representation of Kaiser Wilhelm II is based as a direct spoof on the painting of a boy blowing bubbles ('Bubbles') by John Everett Millais (painted 1885-86).
