The colouring book trend is officially over, it seems, with spoof "kids books for adults" topping the charts instead.
Books, including parody revivals of Enid Bylton's Famous Five series, topped the sales for British bookstore WH Smith over the Christmas holidays.
The series, alongside the Ladybird Books for Grown-Ups, helped sales at the stores rise by two per cent over the previous year.
This comes after the collapse of the adult colouring-in book market.
"They have fallen off a cliff," WH Smith cheif executive Stephen Clarke said in a statement. "Last year was their first year really and people are no longer colouring in the way they were."
