Rupert and the Big Bang started on Tuesday 15th October and with Bonfire Night looming there is a hint of what the story is about.
It originally featured in the Daily Express in 1947 with a subsequent reprinting in colour in the 1950 Rupert Annual.
Rupert and the Autumn Primrose finished satisfactorily after 46 episodes on Monday 14th October in a story featuring an Imp of Spring and the Autumn Elves. If you missed this serialisation in the daily paper, you can read it in your 1955 Rupert Annual.
