So we've already discussed, whether a gallery contract with Van Gogh, if he wrote in the year 200 paintings, among them the ranks of the same? If she can not sell them, then he must give them to somebody else, not salt the same? A Picasso-on 300-500 pieces per year? Gallery will master? or say Pablo, Moderate your enthusiasm ...

Wait, why do you think that an artist must always sell all his paintings?
The agreed contract number of works he gives a gallery owner, and the other stores in the studio, where the problem?
At the same after Picasso's death left a large number of works by Matisse, Bonnard, Giacometti, Vasarely - the same thing. Even Warhol found, much to the delight of his brother, the unsold work!

Note, if they were all sold in his lifetime, it would be relieved of their legal successor of the endless and destructive to their nervous system processes associated with the sharing of the inheritance :)

The problem is that there was nowhere to store ... (or live ..)

LCR, usually about the balance of the sale I already wrote. Maybe when were MANOR, store where it was. Now, even if the artist does not have Roitburd workshop, and must be stored materials and finished products, and land, are unlikely to actively working artist can keep a large portion of the work of, for example, 10 years old.
And then .. they also can steal, pour, mice eat ... correct storage-fooling.

Each picture in its approach and its terms, each artist - his. And if the goals and views from them are the same (about the joint work), then cooperation is obtained. After all, the artist has the right to choose the gallery, but it does not impose conditions, as it should work.
As for me, with the artists consider themselves new vangogami, Picasso and others do not work. Yes, and with printing on 400 products a year - too. It is true that these artists have with me not want to work. So we have mutual-...:)

For example, I start with 5 works (the so-called representational stage). Constant artists represented by ten or more works.

I would like to note that the gallery does not deal with the problems of housing ...:)

Storage, indeed, requires space and costs money - I know this from personal experience and the experience of friends.

But look at another aspect of the problem: what compose the exhibition, if all sold nakornyu, per square centimeter, through the Internet галерейки? What place in museums? Is that such a goal there? ..

The last, unfinished work was, "The Concert", 16 years lay in the basement of rolled-up (because of its size, where a 3 x 6 meters, you could not make it out of his shop without taking off the stretcher) before it is purchased and exhibited Paris Museum of Modern Art. Some work Roginsky early 1980's. GTG were acquired only in early 2000's. and others I have shown in 2005 in his big solo exhibition at Contemporary Art at the First Moscow Biennale - before this opportunity was not there.

There is!
I ask a friend to sell вешь one of the earliest, but he did not sell anything now, getting ready for the big show, and even knowing that from the early exposes not a lot, does not want to sell and wants of the remainder (naprodaval at the time) to have the opportunity to choose before exhibition, selected with the idea, slowly, seeing the mind as if all the exposure ...

But if engaged in storage, then will "place to live" in the house of the artist ...

I do not know what conclusions do ..
Miniatures Activities sure ...

Semen Semenovich, the artist can not produce 5 pictures per year. So you have a non-exclusive contract with him.
And the conditions of our exclusive gallery owners will probably not attract and tongs :-)
