I love this ad for Gnome Bakers, especially the tagline. How unusual could their bread and rolls have been? It comes from a 1973 New York Mets program.
The best part is the old RE phone exchange, assigned to phone numbers from a part of the Upper East Side starting in 1930. It stood for Regent—perhaps the name of a landmark hotel or theater nearby?
A good place to look for old phone exchange signs around the city is near service elevators. This one was spotted in east midtown around 35th Street.
JU is either for Judson, in Manhattan, or Juniper, given to a stretch of Queens.
If we knew the name of the elevator company, we could figure out which one. But alas, no trace of the name could be found.
