The Llano County Historical Museum is the former location of Bruhl's Drugstore.
And they've got the historical marker to prove it:
The marker reads:
"Louis Herman Bruhl (1849-1931) immigrated to the United States from Germany in 1867. He became an American citizen in 1870, the same year he married Leonie Julia Hammale. A merchant and a pharmacist, Bruhl lived in Waco and Rockport, and served as U.S. consul in Italy (1894-1899) before moving to Llano to open a drugstore in 1900. His son Adolph (1876-1937), also a pharmacist, joined him in business. The drugstore building they erected here in 1922 was donated by the Bruhl family to the County Historical Society in 1965 and was later remodeled for a museum."
You can see lots of antique drugstore related paraphernalia inside and was as a variety of historical exhibits.
The area is also home to "llanite", a rhyolite:
