ELMIRA, N.Y. — Police are investigating the theft of a bronze plaque from a monument at Mark Twain’s gravesite in upstate New York.

The superintendent of Woodlawn Cemetery in Elmira said Monday the 12-by-12-inch likeness of the American writer was likely stolen between Christmas and New Year’s Day.

The plaque showing Twain’s image was one of two on a 12-foot-tall, 78-year-old granite monument commissioned by Twain’s daughter Clara.

The author married Olivia Langdon of Elmira and had a summer home in the upstate city. He died in 1910 and was buried in the Langdon family plot at Woodlawn.
