there's some stunning, high-definition pictures. I'm not sure which anchor they were reproducing in the show though, did it specify or not as i missed the first five minutes; Titanic had three anchors, one on the port and starboard bows and the centre anchor (which was, or rather is because it still exists on the sea bed, a whopping 50 tons).
i went to the titanic artifact exhibition in london at the science museum in 2003, it was very moving. They had the famous recovered piece of hull known as "the big piece" - and for good reason. Wish the exhition would travel to the UK again, to my knowledge that was the last visit.
if you're ever liverpool bound check out the maritime museum though - they have a few titanic artifacts on permanent display
and lots more besides.
