Better view of this can be found on my flickr account
This is from John's book - a drawing of where you could find the super markets and shopping centers in and around Fort Wayne. I'm guessing it is from the late 60's - early 70's.
Not much is left from almost 40 years ago.

I'm surprised that some of the downtown places like Murphy's isn't listed here.
