In connection with recent events at Sotheby's, namely, the scandal of Glazunov (
http://artinvestment.ru/news/auctnew..._glazunov.html), I began to wonder: What is often still living artists which are already popular, so do? how it is dangerous for his own wallet? and what to do if you got in this situation? It seems to be working with perfect provenance, as the artist himself from it refuses. For example, I heard that Nemukhin so sometimes comes. As you noticed the main question: what to do in this situation and whether it is worth to buy such "controversial" things?
