Jeff Koons’s 9 1/2-ton "Balloon Flower (Magenta)" (1995–2000) set a record, selling for £12,921,250,00 ($25,752,051; est. on request, in the region of £12 million).
Whyte got lucky later in the long evening, winning
Gerhard Richter’s
powerful and color-charged abstraction
Ypsilon from 1984 for ₤2,729,250
(est. ₤2.5–3.5 million).
A chunk of Sotheby’s success came from a trove of guaranteed property from
the Helga and Walther Lauffs’ collection, which earned ₤18,983,000, double
its high estimate of ₤8.9 million.
Of those 12 standout lots, Yves Klein’s sensational abstraction ANT 131 from
1961 led the pack, selling to a telephone bidder for ₤4,185,250 (est.
₤700–900,000).
"Many bidders exceeded their own limitations," said an exhausted Tobias
Meyer after the sale. "This is a market driven by art lovers."
