1970's vintage 18 inch Super Size Barbie with clothes

Super Size Barbie by Mattel is 18 inches (46 cm) tall, with plastic body and legs, and vinyl arms and head. She has rooted blonde hair, in very good condition, and beautiful painted features.
Barbie is in very good overall condition: no chewed fingers or toes, no ink marks or stains, no haircuts, no smoke or pet odors. She will arrive in her original swimsuit, which has a couple of minor split seams. She also has some extra original clothing and accessories: skirt, long pants, tiara, necklace, barrette, earrings, etc. After the pictures were taken, I found her shoes, and they are also included. The skirt and pants have never been worn, but have a few small spots, due to age. The doll stand is not included.
Shipping cost includes packing and handling. Insurance is optional, but recommended, since the seller is not responsible for items lost or damaged in shipping. I will gladly combine shipping for multiple purchases whenever possible.
