BOSTON (AP) – Boston’s Isabella Stewart Gardner Museum is offering a new $100,000 reward for information leading to the return of one of the items stolen during a notorious 1990 art heist.

The museum says it hopes the reward will help it recover the Napoleonic finial – one of the least recognizable of 13 works stolen by thieves posing as police officers.

Gardner Museum experts say the item should be easy to identify. The 10-inch gilded bronze eagle originally was affixed to a flagpole of Napoleon’s Imperial Guard and dates to 1813-14.

The reward announced Tuesday is separate from an additional $5 million offered for the filial and paintings by Edouard Manet, Edgar Degas, Johannes Vermeer.

Anyone with information should contact museum security director Anthony Amore at 617-278-5114 or theft@gardnermuseum.org.
