This work is too expensive, how do you justify it?

The value of a work of art is tightly connected to the market quotations of the artist. Its value, is therefore determined by a series of objective parameters and, just partly by subjective ones, which however make it recognizable in the art market.
Therefore, the price must be compared to the market quotations, in order to be judged in the right way; this explains why the price of the work isn't really a "cost", but a "value", that you pay in order to own it.
The services offered by have the goal to stress the aspect of the investment (resale, quotations updating, portfolio, receiving the offers from the art market), which becomes not only artistically, culturally, aesthetically, but also economically important.
