Love the crazy-ass exuberance of the imagery in this ad for Dzus fasteners. In general, fastener companies seem to do some pretty sweet signage and collateral — there's the most excellent Brafasco sign in Toronto on the way to the airport, and another (whose name escapes me) on the 5 on the way from LA down to Anaheim (do you have photos of these? Link 'em in the comments!)
(Thanks, Fipi Lele!)
