Katsura poster from Swedish Fine Little Day is a unique X-ray image of a myrtle plant taken by Tor G Nitzelius who was the curator and tree specialist at the Gothenburg botanical gardens. Tor's pictures were discovered by coincidence fifty years after they were taken and developed by photographic artist Johan Brink. Postern Orkidebauhinia looks lovely on its own or combined with several different works of art on a picture wall.
