On the question of Cultural (mis)Appropriation

This Irishman's morning-coffee bowl
was made by a Frenchman in France,
whose glaze techniques on stoneware derive mostly
from the Englishman Bernard Leach,
who was inspired by the great Japanese glazer Hamada.
Japanese ceramics were greatly influenced by Korean pots
which were that country's chief exports...

As Adam Gopnik pointed out on a recent radio talk,
Japanese painters and illustrators (Hiroshige, Hokusai)
were inspired by European painting
to create works, thought by Europeans to be typical
and essentially Japanese,
which then, in turn,  inspired van Gogh, Toulouse-Lautrec et al.
