At the time, Christie's estimated the sales to fetch more than $125 million. The most important works were sold on November 10, 1997 in a single owner sale of 58 works of which 57 sold. Christie's had put the Ganz collection up for viewing for a month preceding the auction at its Park Avenue galleries and at its annex at 308 East 59th Street. More than 25,000 people visited Christie's to view the works and more than 2,000 people attended the auction. For 73 of the 114 works sold in 1997, initial purchase prices are known. In 1997 dollars, these works had cost $4.9 million and fetched $206.5 million (including buyer's premium) in November, 1997. The Ganzes are estimated to have netted revenue of $183.8 million. The annualized growth in value (after inflation) was 12.06%, or 11.74% after seller's commissions. At the time of the auction, it was the largest private owner art sale in history.
