The UK Telegraph had an exhaustive story this weekend on what the headline called "the Renoir wars" -- the ongoing series of lawsuits between the descendants of Renoir and an assistant namd Richard Guino. It began in 1965, with Guino suing the Renoir estate, claiming to be c0-author of a series of sculptures created from 1913 until Renoir's death in 1919 (nine months after Guino's death in 1973, he prevailed in the lawsuit) and continues today with the Arizona lawsuit that was mentioned earlier here.
