I have been in this business for many many years. This is the only bluebonnet by Altheide that I have ever seen. As a matter of fact I have only seen one other landscape. His typical subjects were Mexican Jacals, The San Antonio River Walk, and Mexican Market scenes.
The artist was from San Antonio and was a veteran of World War I. He exhibited at the San Antonio Art League and the Edgar B. Davis Competition.
His work was exhibited Arneson River Theatre, oil on canvas, 16 x 20 at the exhibition, Life Along the San Antonio River, Witte Museum, San Antonio, Texas 2001.
