SVGAllery, start by reading the rules of evaluation in the network ... They are at the top of this section.

The fact that I would like to find information about these paintings, not as objects, as well as the works, ie pictures of themselves do not belong to me, I have only reproductions.
And I'm trying to learn about them as a purely cognitive purposes, and to establish the possible owners of copyright. If I posted a message is not where it is necessary, apologize, then please tell where to obtain such advice
