Black walls under paper?
My husband and I are restoring our 1931 bungalow. Our interior walls are plaster and have visible seams, which I always assumed were due to painted over wallpaper. However, on closer inspection, the paper isn't traditional wallpaper-- it's a rough, brown, almost paper-bag texture, and the walls behind it are black. Does anyone know what this is? I skimmed through Jane Powell's _Bungalow Details- Interiors_ and couldn't find any references to it. I did find an old post about a similar situation (link below), but nobody answered the wall question. If you do know what it is, what should I do with it? Can I just paint over it, or should I strip the paper off? I have to admit, I don't love the look of the seams, but I could live with it.
Sorry, I don't have any pictures, but there is a picture in the linked-to thread.
Thanks in advance for any assistance!
