Cy Twombly's Untitled (New York City) led an evening sale of contemporary art at Christie's London on February 11, achieving £19.6m ($29.9m).
The sale represents the second highest figure paid for a work by Twombly. It comes soon after the $69.6m record for his work, set at Sotheby's New York last year.
Gerhard Richter's Vierwaldstatter See (Lake Lucerne) also sold well, with a final bid of £15.7m ($24m).
Francis Outred, international director and head of post-war & contemporary art for Christie's Europe, commented: "London has seen stellar evening sales for Post-War and Contemporary Art in the last few years - the Christie's June 2012 record of £132million in a single night has never been beaten.
"In that spectrum, our sale stands out as a great result, a huge success. The interest in contemporary art has grown enormously, but at a rate that is sustainable.
"No bubble produces bidders from 40 countries and six continents for such a diverse range of works. I am particularly proud that in the week of Richter's 83rd birthday, one of his greatest paintings - of Lake Lucerne - a place so close to his heart, was so sought after."
On February 10 a new record for Richter's work was set at £30.3m ($46.3m) at Sotheby's London.
In total Christie's realised sales of £117.1m ($178.6m), slightly below the £123.5m ($188.2m) total achieved at Sotheby's on February 10.
