It looks like a hand-drawn map of the Corporation (what is now SNE) network in Sunderland in 1959.
Appreciate some of the estates aren't built, but it's quite amazing how much of the network now is pretty much the same as it was then. 
Here's me thinking the network we have now that I similar to 1987 was bad... I'm going to have to refer back to 1959 now!
