I have a house that is about 90 years old and wish to paint the living room walls. Currently on the walls covering plaster is two coats of wallpaper and a coat of paint on top of those. The plaster does have some small cracks as well.

Is the best thing to do to remove the wall paper with a paper tiger and vinegar or is there something (wallpaper) I can put over the whole thing to take the easy way out and then paint?
