AUGUSTA — The state will issue a commemorative license plate to mark the 2014 World Acadian Congress.

Event organizers say it’s the first time since the United States Bicentennial in 1976 that Maine is issuing a commemorative license plate to mark a significant event.

The World Acadian Congress is held every five years in a region inhabited by Acadians. It draws more than 50,000 visitors from 44 countries and has an economic impact that exceeds $50 million.

In 2014, the CMA will be hosted by the international region known as Acadia of the Lands and Forests, which incorporates northernmost Maine, northwestern New Brunswick and southeastern Quebec.

A commemorative license plate does not have any numbers or letters and cannot replace the legally issued plates.
