The Real Armchair by Adrian Pearsall
Finally I found #8 of the 999 Armchairs Book at Pamono, uhm not 100 % sure, because Pamono only attributed it to Adrian.
You see that if you put too much effort in a search which doesn’t deliver, it is better to turn away, do something else and come back. My last post was a month ago.
