People working at a kiosk on the first floor of Mall of America in Bloomington are selling merchandise and tickets to Vatican Unveiled, a Jan. 10 to Feb. 1 exhibit that will feature the largest collection of papal artifacts outside of the Vatican. Archbishop Bernard Hebda invited Father Richard Kunst, a priest from Duluth and curator of Vatican Unveiled, to display the artifacts as the Archdiocese of St. Paul and Minneapolis celebrates its 175th anniversary.
