Since around 2002, Gignac has been hand picking trash and arranging it in small plastic cubes that are signed, numbered, and dated. Typical cubes include items such as soda cans, candy wrappers, receipts, event tickets, cigarette butts, coffee cups, newspapers, and parking tickets. In the beginning, Gignac’s cubes sold for $10 to a few intrigued tourists. These days, he has sold over 1,300 cubes in 29 countries for $50 and up.
