ST. JOSEPH — A work of public art can spread its influence far beyond its own shadow, panelists at the Krasl Art Center said Tuesday.

The “I Am the Greatest” figures of Muhammad Ali around the Twin Cities have become a role model for young people taking part in a companion after-school arts program, noted Anna Russo Sieber, the owner of ARS Gallery, who launched the effort 10 years ago with artist and educator John Sauve, a panelist along with renowned sculptor Richard Hunt.
