Bettina Dorfmann (Germany) has 15,000 different Barbie dolls, as of October 2011, that she has collected since 1993. Bettina received her first doll back in 1966, but has only been collecting seriously since 1993. Barbie was first released by US toy giants Mattel in 1959. Her full name is Barbara Millicent Roberts, the name of the daughter of Mattel founders Elliot and Ruth Handler (USA). Bettina posed for this photo in October 2011, when her collection surpassed 15,000 dolls. She received her first doll when she was five years old – but it wasn’t Barbie, it was Midge, Barbie’s best friend. She’s now the proud owner of an original (and rare) 1959 Barbie. Got a broken Barbie? Bettina runs a doll hospital, where she fixes broken legs, untangles matted hair and replaces missing limbs! According to Mattel, there are in excess of 100,000 collectors of Barbie dolls worldwide.
