A grayscale patent drawing depicts a football from multiple technical angles, with the top view showing the full oval profile and lower diagrams revealing cross-sectional construction details and seam patterns. The composition uses fine line work and stippled shading to render depth and dimension across the formal schematic layout, giving the image an authoritative, instructional quality typical of early 20th-century industrial 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.
