Several national art writers in town for the opening of “The Art of John Mellencamp” at the Butler Institute of American Art Trumbull Branch in Howland spent Friday touring the Youngstown museum and some private art collections in Trumbull County. A private reception is planned today, and the exhibition opens Sunday to the public. It runs through Jan. 12. Here, Butler director Louis Zona, center, explains the restoration process in the late ’80s undergone by Robert Vonnoh’s “In Flanders Field — Where Soldiers Sleep and Poppies Grow,” one of the best-known works in the museum’s permanent collection.
