It may give the impression that bad artists friendly step by giving paper for certificates, and the genius of all these things do not care, they are alive inspiration and fresh spring water
I think it's not so simple, and automatic compliance "muff = excellent businessman and a wonderful artist = cuckoo" no.
I know of very bad art (I will not name names, I do not want to quarrel with anyone
), which are quite interested in the certification of their works, artists, and good, very attentive to this aspect of their profession.
For example, even if this possibility existed, but what's there, even if I ordered a proper stamp, issued to him Roginsky, and furnished it with all the instructions, he would've never touched it (there are people who consider him a great artist, there are others who do not see it - not the point) - so he had a character - doing the work, he immediately lost all interest in her.
On the other hand, Matisse would be the first in the queue for the chips (I can not even talk about Picasso), and agree, not the last artist of the 20 th century.
This fact is not about how to say this, maintaining the trademark and related profits, and an unblemished reputation of the artist, and as a rule, this question is not very interested in art, and people loved him, whether it is members of his family, his collectors or just fans of his work.
