Mattel has released an official statement regarding the mistake made during production of the Jacob Barbie doll:

Twilight fans! As you may have heard, Mattel’s heartthrob Jacob doll’s iconic tribal tattoo is upside down on a portion of the total dolls produced. Mattel apologizes for the mistake in production and is working to rectify the situation. If you purchased a Jacob doll with an upside down tattoo and wish to replace your doll with an accurately represented tattoo, please call Mattel customer service at 1-800-524-8697 for more information or 1-800-491-7514 if you purchased your doll directly from Barbie Collector.
