Bibby Liner Approaching Rangoon

This incredibly colourful puzzle features a painting by James Mann, thought to have originated as a promotional poster for the Bibby Line. The cutting is in Holtzapffel's later, semi-interlocking and push-fit style with widespread colour line-cutting to enhance the challenge of assembly.
The box address indicates the puzzle to date from post 1932.
