                              The direct reason for the competition was, however, to get ideas for suitable  posters to be displayed in subways, and other public places, as one of the 
                            events during the World Mathematical Year 2000.  In the announcement of the competition, the EMS offered prizes for the three best proposals, but naturally, the hope was to get many other good proposals than those 
                            that would finally be selected for a prize.  And the EMS was not disappointed!
