A Daguerrotype camera will go up for auction at the end of May this year and it's expected to go for an astonishing 500,000 Euro or more.

The wooden sliding box camera was made in September 1839 in Paris by Alphonse Giroux, the brother-in-law of Louis Daguerre who invented the first feasible photographic process. Daguerre signed the box to verify its authenticity, the auctioneers said.

Dauuerrotype cameraThere isn't a record of how many of these type of cameras were made, but the sliding box type was quickly superseded by cheaper and better cameras. The other examples of this type of camera are only to be found in public museums.

This camera was in private ownership, and the auctioneers say, is in outstanding condition and even has a manual in German with it.

The camera is pictured next to a man who is quite a bit younger than the 170 year old antique.
