These are two charming mini dolls from the mid-2010s, both clearly inspired by Mattel's classic style but with different origins. Both dolls are about 13 cm tall and are great for play, as collectors' items, or why not in a period dollhouse?
The left doll is made by "2015 Mattel for McDonald'"s, which means it was part of a Happy Meal campaign, probably within the Barbie range. She has a smooth expression, long dark hair and wears a purple and pink outfit with yellow shoes. Her plastic molding is of good quality for her type, and her arms and legs are movable. A fun detail is the little necklace that is molded in the plastic.
The right doll is labeled "MFG. for BKC. 2017 Mattel", which probably refers to manufacturing for a licensing company or toy line associated with Mattel or a partner, for Burger King. The doll has a simple but cute design, with a blue molded dress and white shoes. Her long hair adds playful character, and the style is reminiscent of younger Barbie or Chelsea characters.
Dolls like these have become popular with collectors of Happy Meal toys and miniature dolls. They represent a specific time in toy history when big brands collaborated with fast food chains and other partners to create playful, accessible products for children.
