A vintage patent document displays four detailed technical drawings of soccer balls arranged in a grid format, each rendered in cross-hatched graphite with careful attention to the geometric panel construction and spherical form. The aged paper, stamped with official patent markings and dense technical annotations, creates a nostalgic monochromatic composition that transforms a simple sporting object into a subject worthy of scientific documentation. 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.
