In this wonderful 1949 film, Mom gets sick and the house gets to be a real mess. Mom is struck with a blindingly brilliant idea! The house will stay cleaner if everyone in the family picks up their own stuff!
Amazing! And the family agrees. Dad, and Bro, and Sis start to clean up, and even do some redecorating.
This is one of those wonderful Coronet Instructional Films, made from the 1940's to the 1970's. They are available at the Prelinger Archives from The Internet Archive, one of my favorite websites!
