3x sections of wallpaper "B&Q Belgravia Décor Ciara Damask".
Each measures between 1m and 1.2m in length and 0.53m in width, so they would be suitable for a single area of around 1.59m x 1m - perhaps the back of a small alcove.
Slight ripples to the backing of one piece as shown, however the top surface appears perfect. Please inspect photographs closely, particularly if you are trying to match existing wallpaper.
