Here is a terrific railway poster by the Californian artist, Maurice Logan…it’s rendered in the flat-colour modernist style of the mid 20C. There’s a nod to the famous Terra Nova poster by Ludwig Hohlwein too…
Logan was a contemporary of Edward McKnight Kauffer…you can see the stylistic similarity between them with Kauffer’s designs for cotton-bale labels and in his posters for London Transport.
These are just the right kinds of image for mission style interiors of the US arts-and-crafts movement.
