Scratch Build a Art Deco Billboard Frame
Whilst these are based upon US prototypes, I have to say they do have a passing resememble to some of the bill boards in the UK Southern Railways Region. Certianly on the lines from Waterloo to Guilford via Surbiton and from Clapham Junction out to Richmond there are strong Art Deco Motifs.
Although in the UK, I would say that you could remove teh wooden framework as the examples i have seen tended to be along side stations and level with the trackside and made of concrete not wood. I dont think the wood vs concrete is a significant issue as the form factor would appear to fit either material?
