I think Cydney is right on target with the parallels between the 1912, Casa Ricardo and the 1913, Corrigan Mansion. I also see some resemblance of the Casa Ricardo end elevations to the work of the Greene brothers of Pasadena and their 1909, Gamble Residence.In 1911-1912, Curtiss undertook a number of projects for the St. Louis, Brownsville and Mexico Railroad in the new town of Kingsville, Texas. One of these was for a tourist hotel called the Casa Ricardo, to be operated under Fred Harvey management. An L-shaped structure with broad eaves and continuous balconies along the interior of the L, the design was one of Curtiss' finest and set the pattern for the Bernard Corrigan residence on Ward Parkway in Kansas City, built the following year.Cydney E.

This image appears to be from the early 1930's judging from the Model A Fords in the parking lot.
Judging from the cars this one is from the 1940's.
