Most wall murals are scenic paintings that are painted directly on an entire wall. Some themes are the Wild West (wth cowboys and horses), Pirate Land (with ships and pirates), Jungle Land (with vines, trees, and big cats), Space World (with planets and stars), and Fantasy Land (with castles and enchanted forests). If you are artistic, you can paint a scene yourself; if not, then an artisitc friend or a paid artist can do it. I have seen canvas murals that can be attached to walls. There are precut holes at the top of the mural protected with grommets. The canvas scenes can be held up with nails through the holes. I have also seen themed wallpaper, but that is too big of a job and hard to put up. Some craft stores have sets of stencils that can be used to create a theme. Hope that helps a little.
