Young & Rubicam has further expanded its relationship with Mattel, adding creative duties on the Just Like You line of American Girl dolls, sources said.

The assignment is new and carries estimated billings of $15-20 million.

The WPP Group shop's New York office, which already handles Mattel's Fisher-Price-branded toys, will work on the business, according to sources.

Y&R's office in Irvine, Calif., has Mattel games, boys' toys and girls' toys. The assignment came after a pitch involving several undisclosed shops, said sources. The other finalists could not be ascertained.

Y&R declined to comment, referring calls to the Middleton, Wis.-based client, which did not return messages.

The Just Like You brand arrives three months after Y&R added creative duties on girls' toys such as Polly Pocket, Disney Princess and Beauty Cuties at the expense of Ogilvy in Culver City, Calif.

The client's creative roster also includes Interpublic Group's Draftfcb in New York (Fisher-Price-licensed toys) and WPP's Ogilvy & Mather in Culver City (Barbie). Ogilvy also serves as the network for distributing Mattel work overseas.
