Did Mark Twain Sign His Name in the Mark Twain Cave?

From the October 13, 2019, Chicago Tribune "Clemens' signature found in Mark Twain cave" by Jim Slater, AP.

Well, since Mark twain wasn't his real name, he would have signed it with his real name, Samuel Clemens.    It had been rumored for many years that he had left his mark somewhere in the cave, but until now, it had not been found.  Now, maybe, it has.  Maybe it hasn't.

A pair of Mark Twain enthusiasts have searched for more than two decades and now say they have found what appears to be Samuel Clemens' signature from his youth scrawled on the wall of the Missouri cave he made famous in "The Adventures of Tom Sawyer."

In the mid-1800s, long before he took on the pen name of Mark Twain, Clemens and his young pals romped around the cave located near the Mississippi River on the outskirts of Hannibal.

As a group of Twain scholars toured what is now known as the Mark twain Cave this summer with cave owner Linda Coleberd, self-proclaimed "Twainiac" Cindy Lovell and two others broke off in the search of this long-elusive signature which was long believed to be among the thousands of names signed on the cave's limestone walls.
