Bought her on marktplaats.nl in February 2010 and fell in love with her. She has no mark on her back, but on her head it says 'Fairlandtoy 1983'. I have been unable to find any information about this doll. She came in the same ballerina outfit that the Siso ballerina wore in the eighties.
The outfit she's wearing now is random, I thought it looked cute on her.
