Thank you yoko.
There seems to have been quite an interest in Japanese woodblock prints in the 1800's
Monet, like many others, was carried away. He began collecting woodblocks by the greatest masters, Hokusai, Hiroshige, Utamaro... "Hiroshige is a wonderful impressionist, Camille Pissarro wrote to his son. "Me, Monet and Rodin are enthousiastic about them."
The fancy for Japanese engravings seized also painters such as Vincent van Gogh, politician like Georges Clemenceau, writers like Edmond de Goncourt or Emile Zola.
