Contra Costa County Subdivisions

Being a second generation real estate professional has some advantages.  My father saved most original brochures from new subdivisions from the 50's till present.  Most include original floorplans and price.  Its nice to have as a resource during listing presentations and such, most of the time the homeowner does not know the original model name, builder etc.  Eventually I would like to scan and add to this blog so everyone could access.
