The museum's name: "Regional," bounded

1993–94 — by 2019

What the documents show: The Artists account left the art museum's renaming undated — the institution is the South Bend Regional Museum of Art in some records and the South Bend Museum of Art today. This pass narrowed the question to its documented bounds. City records of 15 November 1993 and 11 March 1994 use both names inside the same documents: the museum's director, Susan Visser, is styled of the "South Bend Museum of Art" while her institution is the "South Bend Regional Museum of Art." Artists' curricula vitae show the Regional name in use from 1994 through 2003, and the American Alliance of Museums' list of March 2014 still prints "South Bend Regional Museum of Art" — so the longer name was the institution's working name from at least 1993–94 through at least March 2014. By the summer of 2019 the North American Reciprocal Museum list carries "South Bend Museum of Art," the name the institution bears today. What is settled is the bound, and the bound is what prints.
