On a Search for Vintage Maps

So I am currently painting and refinishing a large desk for my sitting room (more on that later), and I visualize a large framed vintage map hanging above it.  After much searching, I have yet to find an affordable solution that fits the space.   During my searches, however, I have found quite a few really great items that I would love to add to my decor, and I would love to share them with my readers (even though I don't have any quite yet).

For instance, this great "Old World Map Wood Box" for sale on Etsy by precambrianman

For only $30.00 plus shipping, I think this would be a great purchase!
