See the old painted, wall ads above. Nice, huh? But nothing special. Such faded advertisements can be found all around town.
But these ads are on the side of building on W. 36th Street and it's neighbor is—Keens Steakhouse, which has been around since 1885. That means that Keens customers have seen those ads as long as they're been around. When Lillie Langtry ate her mutton chops in the early 20th century, she saw the ad for Style Undies and the Eagle Blouse Company. And the businessman today still sees an ad for Style Undies. Nice continuity.
