This is a page from a book my father was given for a school trip he went on when he was 12 in July 1930. All the drawings in the book were made by the schoolteachers, and it looks they used a Gestetner machine to produce it - with these ships' liveries coloured in by hand by the staff.
He lived in London and travelled down to Southampton where he was based for two weeks. This would have been his first time away from home and also the longest he had ever been away in one go. I'm sure this trip was so memorable for him and that is why he kept it.
In the diary section of the book, he says he saw the Duke of York in Portsmouth - less than seven years later he became King George VI.
