Poster Art
The theme of many Europa stamps is poster art, a subject that lends itself admirably to stamp reproduction. In fact, stamps and posters have a lot in common, in that they both aim to put across a message by visual means. Back in the 1920s and 1930s, before commemorative and special stamps were commonplace, there were numerous 'poster stamps' - non-postal labels which, like miniature posters, sought to advertise tourism and industry.
