wallpaper is a good way to hide the crappy plastering
my dad was master painter and decorator and specialised in anaglypta
and his biggest job ,so he told me, was the free trade hall in manchester in the 30,s
took months to do and he was not happy with the hieght of the saffolding !!!
maybe he was the only one mug enough to do it
thats when it was made from rags not just paper and would last for ever and could have just large embossing , if done right
you can still find it in victorian houses sometimes
