Ruth Handler and her husband Elliot, founded the toy company Mattel, Inc in 1945.

Fourteen years later, Ruth would introduce Barbie Millicent Roberts, better known as “Barbie” to the world.

They are very rare and can sell between $500 and $1,000 if in mint condition.

The second answer is more complicated: Mattel had the Twist N Turn waist for the Barbie doll patented in 1966, and that design of waist/body was used for dolls sold between 19.

Featuring his trademark style, Mackie’s first Barbie was The Bob Mackie Gold Barbie, which featured 5,000 hand-sewn golden sequin accents. In the midst of a rash of high-profile celebrity breakups, in 2004 Barbie and Ken made news of their own when they decided they were better off as friends.

They didn’t have to worry about splitting up their things though; the Dream House was always Barbie’s. The avant garde design duo, Phillippe and David Blond, known for glitz and glam created The Blonds Blond Diamond Barbie.

Originally marketed as a racy gag gift that men could buy in tobacco shops, the Lilli doll later became extremely popular with children.

Mattel bought the rights to Lilli, and Handler created her own version.

Given Andy Warhol’s longtime fascination with iconic stars such as Jackie Kennedy, Marilyn Monroe and Elvis Presley, it should come as little surprise that the pop artists would get around to depicting Barbie.

His inspiration came from his longtime friendship with a jewelry designer, an avid Barbie collector with tens of thousands of dolls.

When Warhol asked to paint the designer’s portrait, his friend replied, “Do a portrait of Barbie because Barbie, c’est moi.” Nearly 20 years later, Mattel returned the favor, issuing an Andy Warhol-themed Barbie collectible.

To this day, the Bob Mackie Barbie dolls are some of the most sought after collectibles.

In other words, if you bought a doll that was new for sale in the stores in 1999, removed her from her box and undressed her, she would have the 1966 patent date on her backside.
