If you want to know how not to build a cruise ship, there’s a 300-lot auction at Henry Aldridge & Son in UK on May 28th where you can buy a 32.5-foot-long cross-section of the Titanic. Also, some “keys to first-class lavatories,” dead people’s diaries, “a framed and glazed life jacket presentation” and a mixed collection of morbid, erm, pardon… “modern ephemera.”

Since 1912 when the Titanic got poked by an iceberg and killed Leonardo Dicaprio, extensive investigation has concluded that “excessive speed” caused the sinking… but if you don’t believe it, go play Sherlock on the ship’s schematics for $160K-$240K.
