An art collector says he feels "victimized" after selling a collection of previously unknown Diane Arbus photographs for $3,500, far below their value, the Associated Press reports. Bayo Ogunsanya, who primarily collects African American art, bought a trunk full of unclaimed photographs at a Bronx storage facility in 2002 and sold some of them to Robert Langmuir, who returned a week later asking to purchase more and offering to give Ogunsanya more money if the photographs turned out to be "worth more than you and I think they are." It was only later that Ogunsanya learned from a New York Times article that the photos were by Arbus and would go on display in a Los Angeles Gallery in February and be auctioned next month at Phillips de Pury & Company. Ogunsanya, who claims Langmuir knew the whole time that the photos were Arbus's, took his case to federal court in Brooklyn on Wednesday, asking the court to block or change the terms of the sale and award him unspecified damages. The lawsuit says the photographs are likely worth hundreds of thousands of dollars.
