RARE Nike Oversized Zipper Women's Backpack

This Nike backpack features leather straps attached to a denim frame. The enormously oversized and chunky zipper featured on the face of the backpack works, and is an absolute attention getter. The Nike tag at the bottom of the zipper is an older style, which leads me to believe this is an older promo item or limited release. I can't find information on this backpack anywhere - so this is clearly a rare item. Nike collectors - here's your chance to add something truly unique to your collection!
