Sotheby’s was the chosen cyber venue for dealer/collector, Danny Katz, whose special interests range from Renaissance bronzes to modern British art. Katz, who just turned 72, is a big spender when something excites him, like the Egyptian bronze antiquity he bought at Christie’s in 2012 for £3.7 million against a £400,000 estimate—a record for an Egyptian antiquity. But this felt more like a backroom clearance, with 144 lots priced mostly under £40,000, with several under £10,000. Some items had no reserve so Katz was prepared to let them go for almost nothing, although none did. A small 1960s work on paper by Scottish abstract expressionist Alan Davie had no reserve and was really a giveaway at £2,000 to £3,000, but 44 bids later it realized a reasonable £13,750. With 24 hours to go, 45 of the 144 lots had no bids and had not met reserves, but, with the help of twice-daily email alerts in Sotheby’s newsletters, only 11 were left unsold, and the sale reached an encouraging £2.3 million ($2.8 million), easily surpassing the £1.2 million low estimate.
