To build I want to say that it is a kind of digital printing and when you go closer (from approximately 50cm) also recognizes the pixel structure. The images are mounted on a 4cm wide frame, the but every opportunity to hang missing. But one has to make himself.
Another important detail: The image is an asymmetrical structure. You can see it in the pictures, unfortunately, very bad that the right two pictures hang lower. At first I suspected a mistake. But the support confirmed to me that it is intentional.
