This large wallpaper map was in a Museum in Alaska that wanted to show the Arctic Circle on a map of the world. It was printed on something similar to our wallboard vinyl, which is a wall covering with “sticky note” adhesive.
Wallpaper maps are useful in many ways. We’ve printed a map of the White Mountain National Forest, a number of towns with all the roads and bridges shown, and even a military base.
Rather than gather around a table with half the group trying to read a small paper map upside down, a wallpaper map can be made much larger and everyone can gather around it right-side up!
All you really need to have a wallpaper map printed is a good high resolution file of the area. Much of these are available online, do a Google search and you find what you need.
