HANNIBAL, Mo. (AP) _ Norman Rockwell, meet Mark Twain.

More than 300 magazine covers that Rockwell illustrated for The Saturday Evening Post were to go on display today in Hannibal, the boyhood home of the author Twain.

The Post covers are part of an exhibit housed in the New Mark Twain Museum in downtown Hannibal, about 100 miles north of St. Louis.

Also housed in the new museum are 15 original Rockwell oil paintings that were used to illustrate special editions of Twain's classics ``The Adventures of Tom Sawyer'' and ``Adventures of Huckleberry Finn.''

The new exhibit will be on display through Aug. 15.

Mark Twain was the pen name used by author Samuel Clemens, who was born in Florida, Mo., but moved with his family to nearby Hannibal when he was a boy.
