In 1964 Mattel added a new hairdo style to its line of Barbie dolls. It was known as the Swirl Ponytail Barbie or is also referred to as a side part or swept ponytail. The new style came brunette, blonde, platinum blonde and titian. This doll came with a red swim suit a change from the earlier black and white striped suit. This style Barbie had the Midge/Barbie body with the addition of the word patented on the last line. This mark was found on one side of her butt. They also had a variety of lip colors. Some were red, while others harder to find are light pink, coral, white and a “mustard” color. These dolls have become very collectible today and usually command a higher price than other dolls of the same vintage.
