This is a card flyer, promoting a limited edition trainer, FAC51-Y3, that was designed by Peter Saville and Ben Kelly. It was available at the opening of the Y-3 shop in The Triangle [Corn Exchange] in July 2007.
Here's a link to a great YouTube video of Peter Saville, Ben Kelly, Peter Hook and Miranda Sawyer discussing design, in Kelly's office in 2007. You can see a pair of the trainers on the table in front of them.
