In 1974 an unknown Japanese artist put pen to paper and created a character that would go on to be worth more than $80 billion.The illustration was titled ‘Unknown White Cat’ but you will probably know it better as Hello Kitty. The artist, Yuko Shimizu, designed Hello Kitty while she was working for the firm Sanrio. Fast forward 50 years and Yuko’s friendly feline has been on a fair few adventures including going to space and becoming Japan’s ambassador for tourism. Yuko tells Anoushka Mutanda-Dougherty the secrets behind Hello Kitty’s ‘cuteness’ and introduces her latest character, the stylish French bulldog Rebecca Bonbon.(Photo: Hello Kitty.
