Hi Sharon, this really is a fantastic set up! I believe those are one of a kind antique pieces from France but I can put you in touch with the designer who now has small showroom here in Miami where he sells a lot of things that may be similar to these.
Check out Wade Allyn Hallock, here is the link to his showroom:

Very similar maps at Restoration Hardware store or (best) online.
