Pictures of supermodels Kate Moss [Images] and Gisele Bundchen [Images] (in picture) baring their bottoms are expected to fetch about 1.5million pounds when they go under the hammer.

The pictures are part of a collection owned by German-born collector Gert Elfering, who even had an original image of Brigitte Bardot [Images].

The pictures are part of the 135 pictures that are being auctioned.

'The stylised, idealised female figure occupies a privileged place in Elfering's aesthetic,' the Sun quoted auction house Christie as saying.

A few of the pictures went on display March 10 at Christie's in London [Images], but the sale will take place in New York in April.
