Is this true?

Deducted the following story. In the mid 90-ies, one investor bought for $ 8 million drawings model Helga Testorf American artist Andrew Wyeth, along with copyright. A few years later, he received 1.2 million for participating in these drawings in three exhibitions, 2,8 million in a copyright interest in the publication of the museum catalog, at variance circulation of 400 thousand copies, and 40 million at the resale of these drawings a Japanese collector. Moreover, he retained the right to reproduce images on posters and prints, estimated at 9.12 million dollars.
Astonished. First, I never met with the fact that the product is officially sold with copyright, that it may be a document certifying the copyright, for example, to reproduce this work on posters? Secondly, how many times I gave works from his collection to participate in exhibitions, including foreign ones, no one has ever even hinted about any money. Thirdly, if my works were included in any directories or books, then the surcharge is usually offered to me. As far as I know with my friends-collectors is the case also.
Maybe all this practice still exists, but is held in secrecy?
