The above video runs you through the charts that are posted below from the Evening sales of Impressionist, Modern and Surrealist art. Looking at the comparable sale from a year ago, the market seems to have strengthened simply because the numbers are not so dependent upon the massive Giacometti sale, though they do include the Bacon and Dalí works.
The pattern of the London sales is weighted toward the June cycle. Judging these last sales against their February counterparts, we see that the totals are somewhere around the Summer of 2007, a very strong period in the art market.
Looking at average prices for the Evening sales, we see that the Winter sales are staying on a long-term trend.
The number of lots that sold in the Evening sale is comparable to the Winter of 2005 but the average price is more than triple what it was just six years ago.
