Placards and posters existed from ancient times. The Greek "axons" and the Roman "Albums", with their decorative designs and announcements, were quite similar to today's posters. In ancient Greece the names of athletes and games schedules were written on columns that were slowly turning on an axis. Romans used whitewashed walls in their markets in which sellers, money lenders, and slave traders wrote their announcements and advertised for their products, and to attract the attention of customers they added an attractive design.
