She sold milk on the street of Stockholm in 1833-1834, and attracted so much attention that she became a mascot to be displayed in the salons of the aristocracy for money.
Normally, these girls worked by managing the traffic in the Stockholm archipelago by rowing boats, thereby acting as paid competitors to the independent rower women.
Carin, however, was judged to be too weak for this task, and she was instead hired to deliver milk from Järla gård in Nacka and sell it on the square of Stortorget.
Pilt Carin Ersdotter made a small fortune by this display tour, and after the season was over, she returned to her home in Djura.
The fact that Carin brought with her a certificate assuring her good virtue signed by four baronesses, nine countesses, a count and a governor did not help the matter, and Carin was forced to appeal to her former employer, the owner of Järla gård, Karl von Moliére, a lawyer and official at Svea Hovrätt, for a new certificate.
