Public Enemy No.1. The biggest villain of 1968, mischeviously dropping litter wherever he goes. The Central Office for Information and Keep Britain Tidy want you to be on the side of our heroes, the Litter Defence Volunteers and keep litter to yourself for the sake of the nation and your wallet. This 1968 take on an anti-littering campaign takes a lighthearted prod at litterers, a far cry from other more frightening PIFs on the same topic. So watch out for Public Enemy No.1 in your area and make sure you are keeping to yourself!
