NEW YORK (AP) — Heirs of sculptor Alexander Calder are accusing his dealer of swindling his estate out of tens of millions of dollars.

The New York Times reports ( ) that a lawsuit filed in New York describes art dealer Klaus G. Perls as a tax cheat who stashed millions in a Swiss bank account. The suit also says Perls sold dozens of fake Calders.

A lawyer for the Perls side declined to comment. But in court papers he describes the lawsuit as a "sham and manufactured claim."

Calder was one of the most celebrated American artists of the 20th century, best known for hanging mobiles. He died in 1976. He came from a family of artists: His father was also a sculptor, and his grandfather created a statue of William Penn that's perched atop Philadelphia's City Hall.

Perls died in 2008.
