Did Mark Twain Sign His Name in Mark Twain Cave?-- Part 2

As Linda Coleberd waved the group's lone flashlight around an otherwise dark area of the cave, Lovell says she happened to catch the beam of light as it shined on a signature"  "Clemens," written in pencil.

It wasn't until weeks later that a high-resolution photo of the signature revealed "Sam" etched at the same place, indicating that the signature was that of the famed author and not a relative.

The signature was discovered in July, but details weren't announced until recently, only after several Twain experts were able to study the signature to determine it was almost certainly real.

The cave itself became a tourist destination after the 1876 publication of "The Adventures of Tom Sawyer," as people flocked to the place that inspired some of the book's key adventures.

It wasn't until 1979, after the cave was named a National Historic Landmark that writing on the walls was prohibited.
