Damien Hirst’s formaldehyde fish and Piero Manzoni’s white canvas were among the top purchases during Frieze Week in London as the auction houses sold 231.2 million pounds ($373 million) of art.

As the biggest week-long concentration of art events in Europe ended yesterday, dealers at Frieze Art Fair individually reported brisk sales and the tallies at the auction houses almost doubled from last year’s October sales.
