I think some internationally recognised brand, preferably with local links would be great, but i can't see the likes of Warburtons, or AMS Neve seeing the necessary value in it.....
Maybe someone with historic links to the town like Michelin, although anyone in a figure hugging football shirt might not be so keen on the obvious jokes

(Im excluding charity partners, as that just isn't practical without some benevolent billionaire stumping up the lost revenue)
