Thomas Jefferson had an extensive map collection. Here, state-of-the-art map technology is used to create four 4"-square coasters that fit together to create one 8"-square placemat of any U.S. location you request. Each coated jigsaw piece resists scratches and heat, and is backed with protective cork. Made in England. Please provide full U.S. address and zip code and allow 2-3 weeks for delivery.
