An update: historians Steve Zautke, Ron Rose and Greg Littleton all believe that this was a Watson copy built by Wayne Ewing for Al Dean's Dean Van Lines team, while historian Charles Fawcett believes that the setting is likely in the Southwest, as the flat roofs suggest that this is not snow country.
