'Magic Penny'
This illustration makes reference to school assemblies that I remember as a child. They were held in the gym hall and often made use of the overhead projector. These have probably changed quite a bit since my day, but this is the exact model that I remember at my school in Salford.
More often than not the morning assembly ended with a song, and almost every one of them was about friendship. The one illustrated here was always a popular one, it is a song by Malvina Reynolds.
