The Forbes collection of antique toys is estimated to bring in anywhere from $3 million to $5 million in the sale Friday at Sotheby's.
It includes toy boats, soldiers, motorcycles and board games, including a handmade Monopoly game from 1933.
Another highlight is a 3-foot-long replica of the Cunard (KYOO'-nahrd) Line's Lusitania (loo-sih-TAY'-nee-uh) ocean liner, complete with crew and passengers.
Malcolm Forbes paid $28,600 for the Lusitania at Sotheby's in 1983. It's estimated to bring $100,000 to $200,000 at the upcoming auction.
