Rosenberg Library a history sleuth’s paradise

An Anonymous Patron writes sent along This One on the Rosenberg Library’s Galveston and Texas History Center.
A prized possession is a letter, complete with pieces of reddish-brown candle wax attached, from the private residence of U.S. President Andrew Jackson to Sam Houston, president of the Republic of Texas, in 1844. The letter concerns the notion of Texas joining the United States, and Jackson speaks of the anxiety building in Congress.
