A real piece of Texas history is on display in Tyler. An authentic document signed by Texas Governor Sam Houston, back in the late 1800's. The "land patent" is now on display at Texas True in Tyler. The historical document is what people used to purchase land. In this case, it was for 25 acres in Anderson County. The owner describes her surprise when a friend gave her the document. "You can tell it's signed in ink and it says it's Sam Houston. And I said 'oh my god it is a true historic document!' So I purchased it from her hoping all the while that it is authentic," says proprietress Teresa Farish. The documented has since been authenticated and has been sold to a school in Pennsylvania. The document will be on display until this Saturday at Texas True on Highway 155 in Tyler, from 10 to 5.
