I can't find out much more than the following but I'd love to see this short film. (Another is the 'John Gilpin' short made by Halas & Batchelor with Searle's drawings for the '51 Festival of Britain)
'Created for the UNICEF film, Grain of Sand, 1964. This film tells the UNICEF story simply and dramatically. In the first part, William Blake’s poem, Auguries of Innocence, is narrated over graphic animation by Ronald Searle; the second part features a day in the life of a Tunisian boy. Narrator, David Wayne'

'The plight of children in some parts of the world is portrayed in animated sequences by noted British artist Ronald Searle, the narration following the style of William Blake's poem. There is live footage of a day in the life of a ten-year-old boy in Tunisia. What he observes on his way to and from school illustrates some of the work of UNICEF.'
1964, 14 min 50 s
