A nude portrait of French President Nicolas Sarkozy’s wife Carla Bruni will go under the hammer in New York next month, according to auctioneers Christie’s.

The 13 x 10 1/8 inch gelatin silver black and white photograph was taken in 1993, when Bruni was one of the world’s top fashion models, and is being sold by art collector Gert Elfering.

It is expected to fetch $3,000 to $4,000 when it is sold in New York on April 10, according to the Christie’s web site.
