The Hartford Courant has
this interesting saga of an alleged Calder that was made by his longtime fabricator six years after the artist's death. In 1995, the former president of Microsoft paid nearly $1 million for it, but after the Calder Foundation denied the work's authenticity, he got a refund from the dealer who had sold it to him (Andre Emmerich), who then sued the fabricator. The case was settled with the fabricator taking the work back in exchange for two authentic Calders.
