I like Flat Iron as two words; it doesn’t obscure the origin of the building’s name.
Aside from the streetcars navigating Broadway, the best part of the postcard is the caption on the back: “Facing Madison Square, these two buildings are among the most interesting in the uptown district.”
Uptown for 1905, I guess.
In the center is the still-standing, seven-story Western Union Building, by late 19th century starchitect Henry Hardenburgh.
And look—no Shake Shack!
