missart,
In my opinion, (I was not too experienced
) have the option to buy inexpensive works of little-known artists (under two conditions: that they liked you, and that they had some sort of auction history). Next - one of two things: either try promotirovat their own or simply wait, as the market grows.
For example, sympathetic to me, very lyrical, loose rose on one of our auctions (real sales), four times over the past two years (from 2 to 9 tys.r.), on the other - prices for his work less, although the absolute magnitude much higher. But in any case - is a significant increase in percentage terms.
(admittedly, like mathematics is not too correct, because the picture - piece "goods" from a strictly individual properties. Nevertheless, the trend reveals).
