Tiger, you might be referring to a product called Acoustilead. Not really wall paper but sheet lead that I have used to insulate a shared wall in a condo. I put up the Acoustilead using hot glue and then put a layer of 1/4" sheetrock over it. It worked great and you couldn't see that it was there. Furthermore, being imbedded in the wall, it was not a health hazzard.
Lead Wallpaper? How in the world would I use my X-ray vision to see what the new neighbors look like.
