A photo of what could be history's deadliest iceberg is up for auction after spending nearly a century on a wall in the offices of the law firm that represented the Titanic's owners. There are other photos in existence of the iceberg believed to have sunk the huge liner, but this one comes with some telltale testimony, the Telegraph reports. It was taken by the chief steward on a German liner the day after the Titanic sank, and he wrote that he saw red paint on the side of the iceberg at the time—paint believed to have been scraped off the ship, CNN reports.
"On the day after the sinking of the Titanic, the steamer Prinz Adalbert passes the iceberg shown in this photograph. The Titanic disaster was not yet known by us," the steward writes. "On one side red paint was plainly visible, which has the appearance of having been made by the scraping of a vessel on the iceberg." The BBC reports that this is the first time the steward's testimony has surfaced. The note and photo will be sold as one lot by British auctioneers Henry Aldridge and Son on Oct. 24, and they are expected to fetch upward of $20,000. (Another collector's item: the ship's last lunch menu.)
