The previous review of this was very reasonable -
these are Ministry of Information films from the Second World War linked by Bill Pertwee (Warden Hodges in "Dads Army") - It's interesting to see what The Powers That Are considered it important for the public to know.
I personally was amazed to see an MoI film regarding salvage of bones featuring George The Brewery Ghost that I remembered from seeing on the TV ("All Our Yesterdays" with Brian Inglis) when a child - definitely a plus as far as I was concerned.
The MoI featured well known actors of the day in these movies - there is an appearance by Cyril Fletcher doing an odd ode on the subject of trapping germs in your handkerchief (a message that bears repeating these days as well) - and, wonder of wonders, an "is it?no, it can't be - it IS" moment in one of the films about saving fuel when I recognised George Cole as a schoolboy talking to Alistair Sim, as Nero! (and breaking a violin over Nero's head for wasting fuel!)
Definitely an inexpensive gem and an excellent introduction to the joys of That Which You Need To Know And Consider!
