SEATTLE - Costco shoppers were offered an online deal this month — an original Picasso.
The crayon-on-paper drawing of a face signed and dated by Pablo Picasso was listed for $39,999.99 on the retailer's Web site Jan. 12. It sold Wednesday, said Jim Sinegal, Costco's chief executive, who would not identify the buyer.
The Issaquah-based discount retailing giant may be better known for bulk chicken and cases of soda, but the Costco.com site features an eclectic mix of items, from caskets to computers to sports equipment. ]

But where did Costco obtain this art work??
