This vintage G1  set from  is . It includes a white pony, , and her human friend Megan. Sundance has pink hair and has a symbol with pink hearts and dots in a circle. She is standing in the Bow Tie Pose, with her head turned.

Megan has blue eyes and long blonde hair, she wears a white dress with pink trim. She's missing her shoes, but wears white panties under her dress. Her arms and legs are poseable and her legs are flexible and rubbery so she can ride on top of Sundance or other ponies. 

The elastic on the ends of Megan's dress sleeves is stretched out and there's also some yellowing around the edges, as shown in the 4th photo.

Sundance is still nice and white but has some surface dirt on her body and some dark spots here and here. She also has a pink paint rub on her shoulder under her mane. Her hair is a little frizzy on the ends but is smooth and free of tangles. There's one empty hair plug at the bottom of her mane and her feet are dirty, as shown in the last photo.

Sundance is marked "'83 Hasbro, Hong Kong" on the bottom.
