As the first step in a major rebrand programme, HarperCollins is relaunching 17
of Dr. Seuss´s best-selling books, including such perennial favourites as The
Cat in the Hat, Green Eggs and Ham and Fox in Socks. In response to consumer
demand, the bright new cover designs incorporate much needed guidance on
reading levels, with the standard paperbacks divided into three reading strands
- Blue Back Books for parents to share with young children, Green Back Books
for budding readers to tackle on their own, and Yellow Back Books for older,
more fluent readers to enjoy. Green Eggs and Ham belongs to the Green Back Book
range.
