Unused card of this multipurpose facility, making it sound very grand indeed for this smaller American city.  And why “Five Flags” when you see no flags?  According to Wikipedia, “named for the five flags that have flown over Dubuque; the Fleur de Lis of France, the Royal Flag of Spain, the Union Jack of Great Britain, the French Republic Flag of Napoleon & America’s Stars and Stripes.”   Very minor lower right corner abrasion.  Grade: 2
