A rare 1892 camera designed to look like a set of books could fetch as much as ?80,000 when it appears at auction on 30 November.

Made by American firm Scovill & Adams the camera was built to look like three books bound together by a leather strap. The images were recorded on 5x4in photographic plates.

An 1892 advert for the camera read: ?No lady or gentleman need have any fear that this parcel will attract attention as a camera, for it certainly looks much unlike a camera as anything can, and it is a very striking counterfeit of a parcel of three bona-fide books.?

The camera will go on sale at the Westlicht Photographica auction in Vienna, Austria.

It is estimated to fetch ?60,000-80,000.
