The record price for post-war art was broken twice at a contemporary art auction in Sotheby's, first with a Francis Bacon work and later with a Mark Rothko painting.
The Irish-born Bacon's 'Study From Innocent X' was sold for $52.7m, more than twice the previous record for a Bacon work. It had been estimated to fetch over $30m.
Its post-war auction record lasted just ten minutes, before a Mark Rothko work - 'White Centre (Yellow, Pink and Lavender on Rose)' - was sold for $72.8m.
Both paintings were sold to anonymous telephone bidders.
The 74-lot auction made a total record of $254.9m.
Before this, the highest auction price for an artwork from the period was $27.1m for a Willem de Kooning painting last November.
