This poster was the most widely used on the German side. It has a very simple design, using the three Schleswig-Holstein colours with the word 'German' repeated in each colour. This poster was developed as the result of force majeure: at the end of 1919, it was rumoured that the International Commission aimed to forbid flying flags from flagpoles, or using them as decorations on houses and railway wagons. The Germans therefore put in a request for the approval of this poster and were given permission to print 50,000! The flag prohibition was finally proclaimed on 6 March and on 8 March the Commission's German advisers resigned in protest at this decision. However, the blue-white-red poster could be used unhindered. The flag prohibition was made less stringent as early as 11 March, but by this time the poster was already hanging in rows everywhere. The long, narrow format also made it very suitable for hanging in the windows of private houses – though this was forbidden. German plebiscite poster, drawn by Johann Holtz. 50,000 copies. 60 x 40 cm.
