The headline could easily be from an 1860's issue of the Mahoning Regsiter but instead, it refers to the latest acquisition by the Butler Institute of American Art. It was just revealed that the Butler obtained Norman Rockwell's ''Lincoln the Railsplitter'', the first Rockwell in its collection. The price? A mere $1.6 million. This is the Butler's first Rockwell, closing a gap in its massive collection of purely American art.
