The former securities class action titan Melvyn Weiss is downsizing.

The 79-year-old, Bronx-born Weiss, who pleaded guilty to participating in a kickback scheme six years ago, is selling a collection of more than 140 lithographs, etchings and figures by Pablo Picasso, according to a New York state regulatory filing and first reported by Bloomberg. His waterfront home in Oyster Bay Cove on Long Island’s Gold Coast is also on the market for a cool $18.8 million.
