Is this Times Square, or 23rd Street facing the Flatiron Building? It’s clearly 42nd Street, with the card focused on the New York Times building that gave the square its name in 1904.
But when I first looked at the postcard, I immediately thought Flatiron.
Trolleys, traffic, ladies carrying umbrellas . . . and the Hotel Cadillac is on the left. What stories that building would be able to tell, if only it still existed.
