Mapquestion

I've owned several of these school maps over the years.  They seem to pass in and out of my life.  I guess that's because I'm strangely attracted to them, but don't quite know what to do with them once they're mine.  So they hang around for a little while and then I pass them on.
I can say that I have been happily map-free for a few years now.  But last week I was looking for boxes in a dumpster behind a school and bumped into a history teacher who was on his way out with this one.  Maps of the Ancient World.  We exchanged pleasantries, and now it's mine.
Question.
What to do with it?
I would love to hear your ideas.
