This analysis of the 13-year analysis of February Impressionist & Modern Art Evening sales was made possible with data from our friends at Pi-eX. [Please Note: These charts are ONLY for Impressionist and Modern Evening Sales and do not include Single-Owner sales like last week's Wallace collection at Christie's.] It is available to AMMpro subscribers. Subscriptions begin with a free month for the curious.  Although the Impressionist and Modern Evening sales were lopsided toward Christie's, both houses closed the week happy with their results. That seems to be part of a larger strategy to reduce the size of these sales and continue to increase the sell-through rate across the board in the industry. The number of lots sold in London (exempting the works in the Hidden Treasures sale) were the fewest in a decade. This continues a trajectory of smaller Imp-Mod sales (by lot) that began in the peak year of 2014 and has steadily fallen over six years.
