When I was wee my Dean’s Book of Fairy Tales was one of my most treasured possessions – the others being Dean’s Alice In Wonderland, Dean’s Sleeping Beauty and my extensive Ladybird book collection.
What made Dean’s Book of Fairy Tales so special was the beautiful, spindly illustrations by Janet and Anne Grahame Johnstone, twin sisters born in 1926 who lived and worked together until Janet’s tragic death in a fire in 1979. Anne worked on alone until 1998.
