These are some of the most beautiful posters I've ever seen, most of them hailing from Switzerland in the 40's and 50's (all but the wooden shoe which comes from, you guessed it, The Netherlands). My favourite is the first one, which was designed by Peter Birkhauser and won Swiss Poster of the year in 1944. Gorgeous! These posters are lithographs, which apparently accounts for their intensity of colour and detail. Sadly the use of lithography gave way to less expensive methods in the late 50's, such as photography and offset printing. Tant pis.
