TULSA, Okla. (AP) — The Gilcrease Museum has transferred its copy of the Declaration of Independence to a new home in the most secure section of the recently opened Helmerich Center for American Research.
The Tulsa World reports the nearly 240-year-old artifact —believed to be the only certified copy of the Declaration of Independence in existence —was moved Thursday.
The museum has been transferring more than 100,000 items that make up its archival collection to the center since it opened last September.
Thomas Gilcrease purchased the declaration, along with other colonial American documents, in 1950.
Experts say the Gilcrease copy was likely written in 1776 and that it probably predates the "Dunlap Broadside," the first printed version of the declaration that was published July 4th, 1776.
