Anaglypta
Good old Google Photos has reminded me that four years ago I visited my mum's then new house and we counted ten (10!) different types of anaglypta wallpaper in this three-bedroomed semi (and all painted a slightly different shade of off-white)
All of it went, some quickly, some not so. And a few months ago she sold it and moved again. I trust that I will have that flexibility when I'm in my seventies :)
But for someone, each of those papers was an individual choice and I know from my own childhood experience that if there were ever children living there, the temptation to pick and pop that stuff was almost overwhelming.
Shocking!
