DALLAS - A few pieces of Texas history are hitting the auction block later this month in Dallas.

One of those items is being called one of the most significant items to survive the Alamo.

It's a letter William Barret Travis wrote in 1836 saying he would eventually pay for, or return, the borrowed lumber being used to support the Alamo's cannons.

"Because as the digital age takes over, there won't be significant letters like this. It'll be a digital recording, it'll be an email, it'll be a tweet,” Elon Werner of Heritage Auctions said. “So to see a letter like this is really what brings the whole history to life."

The document along with dozens of other items include books, and photos, and even a map taken from Santa Anna when Sam Houston defeated him at the Battle of San Jacinto.

These items will be part of the "Texana" memorabilia offered at the next Heritage Auction on March 24.

Travis's letter is expected to go for at least $120,000.
