I have a lovely Coca-Cola Picnic Barbie from Mattel.  Barbie is 11-1/2 inches tall, has on red checkered pants, red sweater and blue denim vest with Coca-Cola on it.  Her hair is braided and she has a red ring on.

Barbie has never been reformed from the original box.  On the back side there are picnic cut-outs.  The box is dated 1997 by Mattel.  Inside the box with Barbie there is a red brush, a tiny bottle of Coca-Cola, a can of Coca-Cola Classic and a red Frisbee with Coca-Cola in the center.

The box says this is a Special Edition.
