Attached is a photo of the Casa Loma Hotel in San Angelo that was across from the Shannon Hospital.  My great grandmother ran and owned it until her retirement sometime in the 1950's.  Her name was Ada Poor Steele.
(Her son Charles Steele and daughter Jewel Hutcheson also lived in San Angelo. My grandmother did not.)

 I am unsure of the date of this photo.  Perhaps someone familiar with old cars can tell?
