Official State Flag of Maine
The state flag of Maine was adopted in 1909. It displays Maine's coat-of-arms on a field of blue (the same shade of blue as the national flag). Maine's state seal also displays the coat of arms. All State Flags
The North star* shines above Maine's motto: "Dirigo" ("I Lead," or "I Direct"). The center shield features symbols of the natural richness of Maine - a pine tree (white pine is Maine's state tree, and "The Pine Tree State" is Maine's nickname), a moose (the official state animal), the sea, and the sky.
The farmer is a symbol of pride in Maine's agricultural roots. The sailor represents Maine's strong ties to the sea. A banner below displays the state name; "MAINE" (in capital letters).
*The North star (Polaris) also appears on the state flag of Alaska. Polaris is not merely a symbol of guidance - travelers have depended on it for many centuries to find their way (it always marks due north).
