Hey, I managed to get my hands on a Nov 1955 NY sectional. Check out all the airports in the area in the 50s! Notice LGA, Idlewild as JFK didn't exist. Also, look at the wacky runway positioning to Idlewild and Newark! Look at all the seaplane ports. Cool.
Still want to find older ones if possible, but thought you all would appreciate this. This is just a section of what I scanned. If you want it at a higher resolution, just PM me and I'll send it out to you.
