These vintage National Geographic maps and posters are great for decoration or collection. To use them for decoration, you can simply unfold them and hang them on your wall using tape or a frame. If you want to collect them, keep them in a dry and cool place to prevent damage. When handling the maps, be gentle to avoid further tearing along the fold lines. Since they are vintage, they may be a bit fragile. Don't write on them to keep their original condition. And when folding them, follow the existing fold lines to keep them looking good.
