Classic Chinese Propaganda Postcards from the times of Chairman Mao are emerging from one-time obscurity to capture a prominent place among paper collectibles. These little gems printed in 1950s are surprisingly innovative, funny, interesting and can no doubt serve as an inspiration to many an artist and designer - not to mention their historic and aesthetic value. Prices of these cards are rising as well, often advancing into double figures (naturally, depending on image quality and card condition). The one shown above is titled "The Harvest is Rich and the Children are Fat".
