In general, now looked more in detail everything. Even more confused ...
In different bases - all in different ways. In artnet them like two, one "Carl" the other "C", judging by the pictures. And on artvalue - just "Gutsch C." a picture of both of them with artnet. In the Italian base of the same two, but there is a fee, and even pictures do not open. Perhaps this is one author. So I am writing as found.
