The original Town Hall eagle was looking over its left wing, possibly symbolizing the Revolutionary War, according to a museum newsletter. However, in 1945, at the conclusion of World War II, President Harry Truman authorized a new version of the symbol with the eagle looking over the right wing (the side holding the olive branch) and the symbol has remained that way since.
Since the original Francestown eagle dates to the building of the Town Hall in 1846, it depicts the eagle of that time (the one looking left). The original is kept at the Francestown Heritage Museum.
