A 500-year-old book published soon after Johannes Guttenberg invented the printing press turned up at an auction in Sandy, Utah, a few weeks ago. The owner of the book brought it to the auction in a plastic bag, saying it belonged to his great-uncle and was kept in the attic for years. The illustrated German-language book titled, "Nuremberg Chronicle," was published in 1493. Two-thirds of its pages was said to be missing and in poor condition, made of cotton bond paper not wood pulp. A tattered piece of history, but still worth up to $50,000 at auction.
