For Christie's the sale will be a landmark event, perhaps the largest single-owner sale in its 233-year history.

Christie's is not the only auction house to offer a single-owner sale this fall.

If it does, it would be the highest single-owner sale of Americana ever at an auction house.

The auction on Nov. 10 broke all records for a single-owner sale, totaling $206.5 million.

The auction will take place on May 11 in a single-owner sale.

The total was the second highest for a single-owner sale at auction.

"There is no single-owner sale this time," he said.

Now they are selling everything in a single-owner sale that is expected to bring $3 million to $6 million.

This was the second single-owner sale of the week.

Then, "around 2003, every client seemed to be wanting a single-owner sale," she said, adding, "There was something in the air."
