Christie's had a stronger sale than Sotheby's but both events showed that the market for Impressionist and Modern art may have been affected by the tidal pull of the massive Rockefeller sale which featured a full sales season's worth of Impressionist and Modern art just a month before these auctions. For many years, Christie's was the weaker player in the Impressionist and Modern market with results not unlike those seen at Sotheby's the night before. These last two  June sales cycles were quite different and echo the strong years of 2010 and 2011 when Impressionist and Modern art was seen as a long-term store of value.
