Each pieces is a one of a kind custom made topographic map. These can be made in any size and of any place in the world. National parks, ski resorts, city areas, states, countries etc. For a quote please inbox me with the area you’d like a map of as well as an approximate size. Prices and sizes are approximate and when I find the right slab for your project I can get you the exact size. As of right now the one in the photos is available and is 15×10 inches.
