This later becomes the Dolls of the World Collection.
1976 A Barbie is put in the American Bicentennial time capsule to be opened in 2076. The first black and Hispanic Barbie dolls are launched as part of the International Collection.
But Mrs Handler saw potential and Mattel purchased the rights for Lilli and commissioned a company in Tokyo to create a vinyl teenage doll like Lilli for American girls.
They called her Barbie Millicent Handler after the founders' daughter.
Budding collectors are advised to stick to one genre of Barbie and build from there.
Mint-condition clothes still in original packaging are worth as much as a vintage doll.
