Not to detract from PWG's most excellent adventure in antique wallpaper application, but I'm about to dive into a paper related job myself...My own house...
We're closing this Thursday and after a lengthy two weekend moving schedule I get to start pulling paper from virtually every room of the house...The seller is a pro floor guy who obviously had a wall covering store on the side, because of 3300 sq ft of house, there isn't one room unaffected by wallpaper.
This ain't jes' ANY wallpaper either. This is room upon room of the cheap thin stuff that comes off in bits and pieces no more than an inch square...And all of it is 70s ick--every single bit...
Now a few rooms that have this wallpaper have also had that wallpaper painted over...This is one I've never had to deal with before. I've textured and painted over wallpaper at the customers' request, but never tried removing painted over wall covering...I'm not sure if it will make it easier or harder to remove, but with my luck I'll wind up re-rocking those walls...The striped wall before you is an example of this, wallpaper and border paper painted over with circus tent stripes...

I'm wondering if now wouldn't be a good time to invest in one of those steamers some of you guys seem so proud of...

I'll have to choose a "point A" and work my way out, but this may take some time, as the current economic crisis has me swamped with work this year, and the weather in this part of MN has held me up in spots...
I will update and apprise and complain about wallpaper removal as work progresses...
