DIARY: You must remember

Unfortunately, no-one managed to win last week's quiz. The correct answers were: 1. Yellow Pages; 2. WH Smith; 3. Lloyds TSB. The theme was authors.

This week, we want you to identify the ads and the theme. Fax your answers to (020) 8267 4914/4915 or e-mail campaign@haynet.com by close of play on Friday 31 May. The winner will receive a bottle of Champagne.
