Theodor Kittelsen Troll wonders how old he is

Designs inspired by a charming troll illustration by Theodor Kittelsen (Norwegian 1857–1914). The picture shows a giant troll, sitting on what looks like a rock, but probably is a whole mountain. He appears to be deep in thought, and possibly he has been sitting there for a very long time. A forest has started to grow on the top of his head. Image file digitally (re)restored in July 2020, mainly with the object to enhance the print quality of the posters.
