Vintaga Posters - Historic Artwork & Vintage Poster Prints : Photo Keywords : wwi : The dark days of World War I had come. Across the globe, countries at war created posters that would encourage young men to volunteer for battle. Some of these posters cultivated a sense of national pride; others attempted to demonize opponents. From 1914 to 1918, thousands of different posters were created, and only some of these survive today. Look back to the early 1900s and see what everyday citizens saw posted on street corners, on buildings, and sometimes, in their homes.
