This one I actually have! “The one who started it all,” and at 50c no less!!
It was at an annual flea market, a sweet old lady had her and another Barbie-style horse thing for sale. I looked at 2 different sources in my phone and still could not figure out if she was for real or not, because the images I saw online of her were of her miscolored to pink (and no they were not of her twin, Mayfair.) Also, DBs actually do not have any copyright stamps. The only tip-off I had were her eyes.
I ended up buying her anyway and found out later she was real. I sort of feel bad because there was a little girl who also really wanted her, but ended up buying the other thing instead. Phew.
Remind me to include a picture of her later!
