Details: The United States Flag Act of 1818 set forth a rule that no new stars could be added to Old Glory until the Fourth of July immediately following a state's admission to the union. Thanks to that once-a-year-and-only-once-a-year mandate, New Mexicans hoping to share their pride at becoming the 47th state were essentially forced into committing their first illegal acts as U.S. citizens. This exhibit commemorates that dip into the dark side with 47 Stars, an exhibit of the officially unofficial 47-star flag. 47 Stars joins a collection of long-term exhibits, a year of Centennial topics in the ongoing Brainpower&Brownbags Lecture Series, and a tongue-in-cheek front-window installation that lets you step into a historic photo, all to help celebrate the state's Centennial.
