Between 1927 and 1931, French poster maker Cassandre also worked for Dutch companies such as Gazelle, Philips and Van Nelle. His most powerful work includes the railway and shipping posters which he designed for the Holland America Line and the Zeeland Steamship Company (SMZ). In 1927, the SMZ had moved its service from Folkestone to Harwich, so it is perfectly possible that the poster was produced as a result of this.
