(Sigh! I'd like to buy one great piece of vintage furniture for $ 55!)
A closer look provides info that's useful to describe a setting. Perhaps I want my character to scratch his name into the curved wooden arm of a livingroom chair. I don't have to describe the whole living room suite in order to do so but it sure helps to know what kind of furniture was even plausible during the time period. And depending on the context, I might want to quickly throw out a description of an entire room.
What I find really fascinating is the text itself. The manner of advertising
"Coil Spring Chairs & Sofas Have Been Stopped! "
GET IT NOW-OR YOU WON'T GET IT FOR THE DURATION!
GET IT NOW-OR YOU WON'T GET IT FOR THE DURATION!
(Same screaming message we're used to. Slightly different wording.)
And speaking of words. When was the last time you saw an ad that stated something was "smartly styled" or "very smart suite"?
I'm tweaking my 1940's work-in-progress right now. I don't believe I've used the word "smart" to describe furniture or any other inanimate object. But thanks to a vintage newspaper ad, I have a new context for that word.
Word choice is crucial to setting the tone for a historical piece. And reading old newspapers is an important part of my research process.
That is, if I'm smart.
