One of the finest and rarest travel posters was painted by marine artist Montague Birrell Black in the early 1920s. To help emphasise a vessel’s safety and speed, White Star employed the services of many different commercial artists. The aim was to impress travellers with the size of vessels like Olympic by exaggerating their proportions with a visual trick of reducing the size of any steam tugs or rowing boats in the picture. In reality the vessel in the foreground would have been much larger, but the visual effect worked well and was used not just by White Star but every steamship company to enhance the impression of their vessels.
