This old-timey sign belongs to a store on Myrtle Avenue in Clinton Hill. the UL exchange stood for Ulster.
But what was Ulster? It’s a mystery. A New York Times article from February 1947 announced that 4,200 households in Flatbush “who have wanted telephone installations since the beginning of the war” would be getting UL numbers.
Strangely, Joe’s Superette, on Smith Street in Carroll Gardens, also has a UL number. That’s a bit of a hike from Myrtle Avenue.
Meanwhile, on a residential building in Harlem, the “In Case of Emergency” number above still stands next to an elevator shaft. LE for Lenox Avenue.
