I really love the word 'Thrift', its rare I hear it these days and for that reason this poster from WW1 is being placed up! Encouraging people to buy stamps for the cause in this poster.
You cannot beat an image of Sam with a bayonet. Are they explosions in the background? fireworks? Another poster around the time of the first world war, bringing out national pride in America and encourage people to help out whichever way they can.
