A collection of vintage patent drawings for American football equipment and protective gear fills a black ground, rendered in fine white line work with labeled technical diagrams. Helmets, shoulder pads, cleats, footballs, and player silhouettes in full gear are arranged in a grid format, creating a dense, encyclopedic composition that celebrates the sport's mechanical innovation. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
