Christie's claim the record results are due to "curatorial and sales calendar innovation.'' Incredible sales this year included the Looking Forward to the Past sale which saw the record-smashing sale of Picasso's Les femmes d'Alger (Version 'O') which sold for $179.3 million.

The report stated the half-year total broke down to $4 billion in auction sales, $15.3 million in online sales and $515 million in private sales. The Postwar and Contemporary department has totalled $1.4 billion in 2015 so far whilst Impressionist and Modern Art has made $1.19 billion.
