This Card Range is basedÂ on the hilarious Ladybird Books for Grown-Ups Range. This popular book range has sold over 2 million copies since launching last year and continues to dominate the UK book charts! This cardÂ reads "Happy Birthday to The Wife"Â and the inside message continues "Its time to celebrate and enjoy your special day! (you can tidy up the mess tomorrow) Happy Birthday!" There is lots of space to write your own personal message as well.
