Constitution Day isn't the sort of occasion that gets great attention, save among members of the Federalist Society or devotees of James Madison, one suspects.

But 2012's anniversary will bring significant celebrations to Virginia--at Mount Vernon, Montpelier and George Washington's Birthplace.

Mount Vernon will herald the 225th anniversary of the signing of the Constitution by unveiling George Washington's annotated copy of the Acts of Congress.

The rare volume garnered global attention this summer when it was sold, breaking auction records for an American historical document.

At noon Monday, it will go on view in the Donald W. Reynolds Museum and Education Center, where it will remain through the national observance of George Washington's birthday on Feb. 18, 2013.

Bearing the first president's handwritten notes, the well-preserved book includes Washington's copy of the Constitution, the Bill of Rights and other legislation passed by the first session of Congress.

With it will be--exhibited for the first time together--Washington's first draft of the Constitution, which displays his handwritten notes recording the Constitutional Convention's handling of each proposed clause.

The documents will provide "an unprecedented view of history in the making, through the mind and actions of America's first president," Mount Vernon says.

Washington presided over the convention and its drafting of what the National Archives calls one of America's "Charters of Freedom." Without him, it's unlikely the fractious states would have mended their differences--or perhaps convened the meeting at all.

Celebrating the Virginian's successes in fighting to establish our country and determining the shape of our government will be front and center Sunday at Washington's birthplace on the Northern Neck.

From noon until closing, the national monument on Popes Creek will hold programs for all ages to mark Washington's great achievements.

At noon, children will read a history book about the Constitution on the Visitor Center's observation deck. At 2 p.m., historian Phillip Greenwalt will present "The Constitution and its Remarkable History" in the auditorium.

Visitors are invited to test their knowledge of the Constitution with trivia, games and puzzles to earn a Constitution Day certificate. They can also sign the Constitution with a quill pen in the Visitor Center and see exhibits on the founding document.
