The art deco Metro station signs in Paris have more than stood the test of time. In fact, I think the patina they have gained over the years makes them more alluring. It's easy to imagine Hemingway and his cohorts rushing down these stairs past this sign nearly 100 years ago.
I find it hard to believe that any new underground train line in today's era would spend the time to have artisans craft such appealing signage. It reminds you that there was an era where the train was a luxury and not a second or third choice.
