This is a HEAD ONLY from the 1988 Island Fun Teresa doll that had the twist 'n turn waist.   Neck back marked c/ Mattel 1982.    Very good used condition - item cleaned, hair washed/conditioned, just brushed out.  This face mold was used throughout the 80s for the Mexican, Latino Spanish and Asia Pacific Islander dolls.  I'm a Barbie collector and have researched this item.
