"Removing wallpaper revealed drywall that looks like it was screen printed. Is there a name for this type of ‘decorative’ drywall? House was built in 1950, Upstate New York."
A: "I dont think such ‘decorative drywall’ exists and this could very well be old, thin, well-stuck wallpaper. Which could be result of many layers of wall paper over the years and the adhesives layering on the original wallpaper to create the look as if its not actually wallpaper."
