*Note: In May, the Texas Historical Commission received the unexpected news that the owners of Southwell Company, the business that has produced our historical markers for more than fifty years, sold their firm. The Texas Historical Commission is searching for a vendor that can accept the volume of markers ordered annually, develop a quality product, and create and deliver markers in a reasonable amount of time. The agency must follow state guidelines and processes in selecting a new vendor. As of December 30, 2019, we are still in the process of searching for a new foundry to cast our markers. A Request for Proposals (RFP) has been posted. You may view the RFP at: Both the Marker Replacement and Supplemental Plaque forms will be posted as soon as possible, please continue to check this webpage for further update.
