These dolls appear to be the 1962 original Tammy versions, with the bubble cut ponytail hair, red lips, side glancing blue eyes. They come with a tennis racket, their original shoes, one original dress hanging in the closet, which is located in their Tammy case - and the Tammy wearing the red leather skirt has a matching red leather purse. 

There are a few flaws in this package - the case has a small tear between the handle and the side of case, the interior case shelf is loose and needs to be repaired to be affixed back to the case wall, and the lining on the interior lid of the case is loose. The dolls though are flawless.

Because these were only produced for a few years, these are hard to find. In the rest of the world they continued on for much longer than in the USA. More info below.

FROM WIKIPEDIA (I think this was from a few years ago....)

History

The doll was loosely based on the character "Tammy" in the 1957 film Tammy and the Bachelor.[2] Tammy was produced in three versions: the first with straight legs, the second released in 1964 with bendable legs, and the final version released in 1965 was an older-looking doll titled "Grown Up Tammy". This doll was also released in an African American version.

In 1965, Tammy's popularity waned and she was discontinued in early 1966.

Friends and family

Dolls released by Ideal that comprised "Tammy's Family" included Mom, Dad, brothers Ted and Pete and sister Pepper. Other "Tammy's Family" companion dolls included Dodi, Salty, Misty, and Montgomery Ward's exclusive Patty and Bud, Tammy's boyfriend, which was produced in small numbers near the time when Ideal ceased production of all Tammy Family dolls.

Legacy

Although production of the Tammy doll was fairly brief, the doll inspired the United Kingdom's bestselling teenage doll, Sindy. Sindy was released in 1963, one year after Tammy, and Pedigree Toys obtained permission to use Tammy's tag line, "The Doll You Love To Dress".
