Proving that good design ideas never go out of style, this 1935 ad for Armstrong floors contains some great features that we'd be mistaken to think of as fleeting trends: chalkboards, oversized maps, and the clever use of built-ins for shelving, bed and workspace. Even the boldly geometric polka-dotted upholstery is spot-on.

(We have to admit, however, that, ironically, the flooring does not quite work for us.)
