One of my favourite books from my child hood is 'The Possum That Didn't' by Frank Tashlin. It is a story of a little possum that would hang upside down in his tree; smiling at the world. Until one day the 'people from the city' came on an outing to the country side and saw the possum hanging upside down; thinking he was sad. As the story goes on the 'people from the city' take the possum to the city where 'everyone is happy' to make him SMILE. And as time goes by the possum gets sadder and sadder until his mouth turns down...into what the city folk think is a smile! Written and illustrated by Frank Tashlin in 1951; this wonderful book with a message that is still poignant today is part of series of books by the same author. Another one of his books of this time is The Bear that Wasn't. This title was made into a cartoon in 1960 and is one to try and look up... What I love is the simplicity of the illustrations that draw you in with their graphic wit and emotional depth; all in Black and White from this first edition of 'The Possum That Didn't' 1951.
