As the United States celebrates its 250th birthday, Texans have a chance to see rare documents from the founding of the nation. Freedom Plane National Tour: Documents That Forged a Nation, presented by the National Archives Foundation, will be on display at the Houston Museum of Natural Science through Monday, May 25.

Admission is free to the public, but is separate from general admission to the museum. Space is limited, and passes are available on a first-come-first-serve basis. Non-members should expect long waits or the possibility that the day's passes are sold out. Only museum members can reserve passes for specific times. Flash photography is prohibited due to the fragile nature of the documents.

The collection includes a rare engraving of the original Declaration of Independence; official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton; one of the drafts of the Bill of Rights; the Treaty of Paris, the documented that recognized America's independence from Great Britain; and the tally of votes approving the Constitution.

The national Archives specifically chose Houston as one of only eight cities in the country to host the exhibit as a means to help the documents reach a wider audience outside of the main hub of semiquincentennial events in New England and the Washington D.C. area.

"[This was] one of the things we decided when we put the tour together because we wanted to be off the East Coast," said Patrick Madden, CEO of the National Archives Foundation, who was on-site for the exhibit's opening in Houston. "There's a lot of 250th celebration stuff happening in the original 13 colonies. How do we get it to major markets where larger numbers of people can see it?"

The prize of the collection is a rare engraving of the original Declaration of Independence. Secretary of State and future president John Quincy Adams commissioned 200 exact replicas of the document from engraver William J. Stone in 1823. Less than 50 now remain. Madden joyfully pointed out that there are errors in this document, a potent reminder that the men who forged a nation made mistakes.

"There's a couple of typos in it where they had to make corrections," said Madden. "So even the founders, you know, they're all human. That resonates because here these people are making this move against the most powerful nation empire in the world and putting their lives on the line for a country based on ideas."

Other impressive parts of the collection include official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton and one of the drafts of the Bill of Rights. Many states would not ratify the constitution until certain rights were included in the document, leading to Washington going on a national tour assuring state leaders enshrining protections was first on the list. The draft copy on display specifically shows the First Amendment in progress.

Houston is the fourth stop on the exhibition's tour, which will take the documents to Denver, Miami, Dearborn, and Seattle through the summer once they leave the city. Freedom Plane is just one part of a larger patriotic celebration at the HMNS, which includes a film series celebrating American science and culture and general Americana decoration throughout the main hall.
