Documents an exceptional postcard collection begun in 1889 by a Swiss entrepreneur, gathered on his business trips as mementos of travel. When word of the hobby reached friends and relatives, others began sending picture postcards as well, and after his death, his daughter continued to seek out postcards from around the world. The collection now includes 54,000 postcards from 140 countries, with especially impressive examples from the height of the picture postcard's popularity -- a wonderful testament to one man's obsession and a new way to experience the postcard as artistic expression and communication.
