When I first saw this map posted by Peter Lloyd a few days ago, I recalled seeing it in my Queens phone books in the 70s/80s when I was a kid. I decided to recreate this as a 2024 service map. Peter has more info about the 1975 map, very fascinating research by Peter! You can find him on multiple social media platforms including his website: nycsubwaymap.org
You might notice that the unknown designer for New York Telephone Co. may have copied the base map of the 1967 MTA subway with a hint from the Hagastrom subway map (route labels along each line)
If you see any errors, feel free to let me know.
Enjoy!
