For sure, it is hard, or impossible, to compare and tell that van Gogh is better than Cezanne, or Picasso better than Vermeer, even only juging on technical skills.
My great aunt was contemporary with van Gogh, Cezanne, Picasso and her hobby was paint. For sure she does not have same skill level and is totally unknow
and not recognized as top level of 20th Century painters.
Why do you quoted Van Gogh, Cezanne, Picasso Vermeer ... and not my great aunt ? Because are recognized as top level painters on their group/style/time period.
I am not looking for a ranking: first, second, third, ... just want to know if there is a publication or a list, like the Fujishiro for sword, that identify the top level / recognized tsuba artists.
Sorry if my English make missunderstanding in my request. However, interesting discussion.
