It's not wall papered, and I think they just painted onto the plaster/brick/something underneath.......need to strip is asap - as I think a bare wall will look better for potential buyers than what it looks like right now - it will be sorted properly either next weekend, or the weekend afterwards (by someone that knows what they're doing) but I want to try and get the paint off this weekend.....(it's currently all flaking and peeling off, and is the wrong type of paint so it looks horrible)
