From my personal collection I offer a 1980 International Barbie Doll. Convention "21 Years of Barbie" held in NYC, NY October 15-18, 1980. Mattel donated Beauty Secrets Barbie dolls wearing "21 Years of Barbie" banner to convention goers. Convention gifts included a pink convention book, and a miniature gold toned plastic Barbie charm. The 60 page program / booklet has a lot of great information.
Only 150 sets were made. The box has shelf wear but has never been removed. Please see pictures as part of description.
