Colin Gleadell has some interesting data on the market for Surrealist works. Last year, Christie’s Surrealism sale pulled back to just under £29.5m, a substantial retreat. This year, the estimate range is £33,210,000-45,530,000, a shot at bouncing back:

According to the late Robin Duthy’s Art Market Research Index, now managed by his son, Sebastian, the surrealist market witnessed a boom between 2006 and 2013 when prices were increasing by an average 20 per cent a year. Christie’s annual surrealist sales in that period jumped from £10 million to £37 million, and in 2015 leapt to £66.6 million. At that sale it was noticeable how many Asian bidders were coming into the market. But surrealism is not where the main contest is.
