Charles Shepherd, known as Shep, studied the art of stained glass windows under Paul Woodroffe. "Simplicity in design is enforced upon the worker in stained glass by the nature of his material, and it was this that produced that preference for simple outlines, bold masses, bright colours and emphatic style which in course of time were to characterize [Shep's] poster work" (Art and Industry, June, 1937, p. 228.) After World War One Shep began working under Herrick at the Baynard Press in London, and shortly thereafter became the head of the studio. He designed posters for the Southern Railway, British Rail and the Royal Mail Packet Steamship Company. "His Southern Railway Heraldic Maps convey the dignity of the great railway. In 'The Gateway of the World' . . . the decorative flags that seem to flutter, the items of decoration and the almost realistic ships, tell the story of the Railway's services in a decorative and colourful manner" (Art and Industry, June 1937, p. 233). Art and Industry, June 1937, p. 229.
Please note 1936 poster has Nazi flag representing Germany, otherwise phenomenal graphic design.
