FNY Correspondent Gary Fonville:
This is what I believe to be a sign that dates from the White Plains Road line’s construction around 1915. The only other extant vintage IRT sign still displayed is over the escalator at the President Street station on the 2 and 5 lines , and the reason why it has survived and hasn’t been appropriated is because it’s over a moving elevator in direct eyesight of the station agent.
[Not sure — I don’t think the IRT was using blue enamel signs at the very beginning, though I could be wrong. –ed.]
