Three Rivers Michigan 1977 directory vintage interesting

I have a 1977 Three Rivers Michigan vintage phone directory. This is a very interesting item with lots of ads from businesses from a bygone era. It is really interesting to go through. The back cover does have a crease in the center. The front cover has some stains and the book has normal signs of wear. I have given several pictures of it so please check those out. If you have any questions please ask.
