Read a book, flip off a Nazi: when reading meant resistance – in pictures

In the early 20th century, books became a meaningful symbol of freedom and democracy for the US, UK and their allies. A new exhibition in New York showcases colorful posters encouraging the public to donate and help supply soldiers with reading material. Reading Under Fire: Arming Minds & Hearts During Wartime is on display until 1 November at Poster House. All words and images from Poster House and curator Molly Guptill Manning
