When you walk into an art gallery, and ask the price for either a painting by a world-renowned artist or a work by a relatively unknown emerging artist, whether the answer is US$75,000 or US2,500, you have the right to expect that the price is based on either actual sales figures of similar works by the artist, or other art dealers offering similar works, or recent auction sales. If it is a reputable gallery, the gallerist will be delighted to discuss the price and relate to you why the work is priced as it is.
