Civic & regional flags
Flags of cities, provinces, states, cantons, territories, and other subnational governments. These two records show how heraldic devices and historical events become civic geometry.
Maritime & signal flags
Ensigns identify authority or nationality at sea; signal flags communicate defined messages. Records in this family always separate identity from operational meaning.
Historical flags
Superseded designs with a precise period of use. Historical entries store both start and end dates so they cannot be mistaken for current flags.
