This sculpture "Man on stool" is situated in the Westerparc in Amsterdam and made by Ronald Tolman (1948). His sculptures are mostly man figures who have some action. This man in fact is watching another sculpture, an abstract ornament, see below.
This abstract ornament is made by Liesbeth Pallesen (1955). Originally she had made a bronze schulpture but it was stolen in 1995. In 1996 she was told to make another one.
Here you see them together.
