This amazing vintage find is the original Superstar Barbie Halloween costume by Collegeville. It features an ABS plastic mask with vinyl smock dress. Copyright 1978 Mattel Inc. Has the original box although it has fallen apart.

Listed as size small 4-6. Mask is 8" tall, 7" wide.

The condition is as shown in the photographs - the mask has cracks along the edge and the back elastic is gone. The vinyl smock has wrinkling, tape on the back and some light soiling. Box lid has broken apart. These costumes were not made to last, so it's a rare find and in rather fragile condition.
