If you are looking for a 1930s vibe for a room (or indeed, a house), you might want to check out this Deco Diamond wallpaper by Hemingway for Graham & Brown.
Love the sharp lines that make up the diamonds, which in turn make up a design that's almost hypnotic, but very reminiscent of the '30s. Might be a bit much for an entire room, but for a feature area, it would certainly have impact.
Each run is 52cm wide and 10m long, with a roll costing £30.
