George Washington’s Oath of Allegiance, 1778
Tickets are FREE to the Freedom Plane National Tour exhibition. But, all guests must reserve a timed-entry ticket in advance. You can do so here.
The tickets are JUST for the exhibit. To explore the rest of History Colorado Center, admission is $20 per adult and free for kids and members.
The Freedom Plane National Tour is taking flight to honor 250 years of American independence.
These inspirational and aspirational documents – which have never before traveled together outside of Washington, D.C. – include:
Original Engraving of the Declaration of Independence, 1823: One of only about 50 known engraved copies of the Declaration of Independence, printed from a copperplate of the original. Commissioned by John Quincy Adams and made by engraver William J. Stone, the engraving captured the size, text, lettering, and signatures of the original document (on loan from David M. Rubenstein).
Articles of Association, 1774: The most important agreement at the time that was adopted by the First Continental Congress and signed by all 53 delegates, which urged colonists to boycott British goods.
George Washington’s, Alexander Hamilton’s, and Aaron Burr’s Oaths of Allegiance, 1778: Oaths of Allegiance that all officers of the Continental Army signed during the Revolutionary War.
Treaty of Paris, 1783: Signed by John Adams, Benjamin Franklin, and John Jay, this Treaty with Great Britain formally recognized the United States as an independent nation.
Secret Printing of the Constitution in Draft Form, 1787: A rare copy of the U.S. Constitution in draft form, with a delegate’s handwritten notes made during the Constitutional Convention in 1787.
Tally of votes approving the U.S. Constitution, 1787
Tally of Votes Approving the Constitution, 1787: The voting records of the Constitutional Convention reflect the debates, resolutions, and eventual vote on the final text that would become the Constitution.
Markup in the U.S. Senate of what would become the Bill of Rights. After the Constitution was ratified by the states and became the supreme law of the land, Representative James Madison proposed a series of amendments. Several states advocated for additional protections for individual liberties.
This is the U.S. Senate’s “markup” of what became the Bill of Rights. On September 25, 1789, Congress passed these 12 amendments, and they were sent to the states for approval. Articles 3 through 12 were ratified in 1791, ensuring such basic American freedoms as the right to freedom of speech, freedom of worship, and freedom of assembly.
History Colorado Center is open daily 10 a.m. to 5 p.m.
1200 N. Broadway, Denver.
