What is thought to be the world's oldestcamera is to be sold by auction in Vienna on May 26. Dating back to 1839, the Daguerreotype, encased in a sliding wooden box frame, was made by Susse Freres of Paris.

The camera belongs to a US-based scholar and was inherited from his father, a technical photography professor at Munich University. The starting bid is $132,000, but the final price for the 168-year-old gadget is expected to be way past a million euros ($1,329,000).
