Although he is best known today for his woodblock prints of Japanese and Chinese landscapes, Pieter Irwin Brown also made a living as an artist of advertising posters. While living in London, England in the 1920s, Brown designed posters for several railroad companies, including London's Tramways, as well as the National Radio Corporation, and the London County Council. Brown worked with a man named Rickman Ralph, who ran the financial side of their business, 'Ralph and Brown, Poster Artists'.
In the early 1930s, Brown designed at least two posters for the Japanese Government Railways. These posters were intended to promote foreign tourism, and they may have been sent abroad for use as advertisements in the US and Europe. The daytime poster depicts the Itsukushima Shrine at Miyajima, historically considered to be one of the three most scenic spots in Japan. The night scene is similarly composed of traditional symbols of "old Japan", depicting a torii gate and stone lanterns against the shadow of an old Japanese farmhouse. Despite the rather nostalgic subject matter, Brown used clean lines, flat areas of color, and a minimal palette to create strikingly modern poster designs.
