PHILADELPHIA (CBS) – “Titanic: The Artifact Exhibition,” opens in the Franklin Institute on Saturday, marking the 100th anniversary of the loss of one of the world’s most famous passenger liners.

Mark Lach, creative director for the traveling exhibition, says it has been 10 years since the show debuted in Philadelphia.

For those who missed it, he says it’s a must-see event. For those who did catch it last time, Lach says there’s so much more, including additional artifacts and, “We talk a little about the science and the technology of recovering the artifacts, the 2010 dive to the wreck site that gave us a 3-D mapping of the entire wreck site.”

But Lach admits, one of the most-talked about parts of the exhibit is when visitors get to the reproduction of the ship’s grand staircase. “They’ll look at it, they’ll go: “Oh, it looks just like the one in the movie.” Well, of course, the one in the movie looks just like the real one as this one does.”

The exhibition features more than 300 original artifacts recovered from the Titanic’s underwater debris field.

It will be based at the Franklin Institute until next April.
