liquidity in the art - the opportunity to sell in the desired time frame for the desired money. As correctly pointed out, the faster you want to sell, so get ready for big discounts and vice versa - the more time, more chances to realize the desired price. Among other things this figure is affected by:
1. Uniqueness - the growth of quality and uniqueness of art is growing in proportion to the number of buyers. How do you understand the works of Rembrandt, El Greco, Filonov, Malevich to find a buyer for the desired price is easier than even the first-class works of Monet. Or consider the historic significance of the work - for example, it belonged to some famous person, or it displays an important event. This also affects the liquidity of work.
2. Size - large proizvedenieya (more than 1,5 x1, 5) as easy to sell, as well as very small (on 15x15).
3. The situation on the market - if there is demand for a particular artist, the probability of a quick sale of his work increases. If the artist is known, but so far "out of fashion," then sell it hard. As an example of Burliuk, which at the peak fly like hot cakes, then had a couple of years, not particularly in demand, and now again poluzetsya attention of buyers.
4. And, of course, the very theme of work - that it displays. Some people like landscapes, some abstract, etc.

In general, sales of work - is it a coincidence huge number of factors. But the main thing - it does not hurry.
