A Vintage Photos Theme Park photo for the theme of steps, stairs, staircases.

This is a real photo postcard of young women standing on the steps leading up to the entrance of a building. They're wearing uniforms with scarves or neckerchiefs, and the banner they're holding simply says, "Flash." In the corners of the banner are what seem to be drawings of stylized top hats. Peeking out from below the banner are two pairs of what might be athletic shoes.

Although someone over on Flickr amusingly suggested that this might be an early example of a flash mob, I suspect that these young women belonged to a club or sports team at a high school or college. But I'm not sure what "Flash" meant to them or why the top hats -- if that's what they are -- appear on the banner.
