After its Essl Collection sale on Monday kicked off the Frieze-week frenzy, Christie’s returned on Thursday night with its main event of the week.

Peter Doig’s first tropical painting led a carefully edited postwar and contemporary auction. The house tried to catch the prevailing mood favoring young artists—like the many being exhibited at this week’s fairs—and the German masters now on view in many of the British capital’s biggest galleries.

Still, the top lot was Doig’s “The Heart of Old San Juan,” dating from 1999, showing an emerald-green basketball court by the sea. The tranquil painting attracted some interest in the salesroom and sold for £4.56 million (about $7.26 million).
