Ours is a visual age. We are bombarded with pictures from morning till night. Opening our newspaper at breakfast we see photographs of men and women in the news, and raising our eyes from the paper, we encounter the picture on the cereal package. The mail arrives and one envelope after the other discloses glossy folders with pictures of alluring landscapes and sunbathing girls to entice us to take a holiday cruise, or of elegant menswear to tempt us to have a suit made to measure. Leaving our house, we pass billboards along the road that try to catch our eye and play on our desire to smoke, drink or eat. At work it is more than likely that we have to deal with some kind of pictorial information, photographs, sketches, catalogues, blueprints, maps or at least graphs. Relaxing in the evening we sit in front of the television set, the new window of the world, and watch moving images of pleasures and horrors flit by. Even the images created in times gone by or in distant lands are more easily accessible to us than they ever were to the public for which they were created. Picture books, picture postcards and color slides accumulate in our homes as souvenirs of travel, as do the private mementos of our family snapshots.
