What was the logo of IRT (Interborough Rapid Transportation Corporation)?
I am not sure, but it looks like the designer that was in charge of the corporate image of the first NYC subway company really liked wings.
A genderless angel holding a winged subway wheel from an $100 IRT stock certificate I recently purchased for 25 bucks.
A logo I scanned from a reprint of “Interborough Rapid Transit ; the New York Subway , It’s Construction and Equipment” which I mentioned before. Wheee. Notice the third power carrying rail. Cute.
