1979: The 'test card girl'
Barry Took meets Carole Hersee - better known as the little girl featured on test card F - and finally gets to finish that seemingly interminable game of noughts and crosses with her.
Carole became the most aired face in British Television history, wracking up an estimated 70,000 hours of screen time between 1967 and 1998.
