The Caldwell House is a scale version of the home in which the Caldwell family raised their children in Audubon, Pennsylvania.  Given to Mrs. Caldwell in 1990 as a gift honoring her on her fiftieth birthday, she invited her grandchildren to assist in furnishing the home - including novelties such as a computer in the boys' room (highly likely) and a pet monkey sitting at the computer (not quite as likely).  The home is still in Audubon, and has been repurposed as the offices for Audubon Family Dentists.
