A technical patent diagram illustrates a football from two angles, rendered in white linear drawings against a solid black ground with the distinctive header "United States Patent Office" at the top. The composition presents both a side profile and overhead view of the ball's internal ribbed structure and external paneling, signed by the inventor in the lower right corner with the precise, clinical aesthetic of vintage patent documentation. For a sports enthusiast's office, game room, or athletic-minded workspace. Made to order by hand at our own Denver facility, it arrives as nine wood panels, each a half-inch thick with a keyhole on the back so it hangs easily. The natural grain shows through the artwork, so no two come out exactly alike.
