The artist, Kristen Visbal, "made twenty-five editions of 'Fearless Girl' and two artist’s proofs. She sold eight replicas, for up to two hundred and fifty thousand dollars, including one to the law firm Maurice Blackburn, in Melbourne, Australia, and one to an investor in Oslo, who put the statue in front of the city’s Grand Hotel, which he owns. Visbal also sold more than a hundred miniature versions for about six thousand dollars each."
