Modigliani nude sells for record price at Christie's auction in London
Nu couche (Reclining Nude) was sold at Christie's in New York to a private Chinese collector.
It had never been sold at auction before, having been in the same private collection for about 60 years.
The top price achieved for an art work at auction was Picasso's Les femmes d'Alger, which sold for $179m ($118.5m).
Christie's global president Jussi Pylkkanen explains why Nu couche is so significant.
