A detailed technical patent drawing displays three views of a tennis racket alongside cross-sectional diagrams and component specifications rendered entirely in black ink on white paper. The composition captures the mechanical precision of early 20th-century patent illustration, with fine lines and numbered annotations documenting the racket's construction from handle through the woven string head. At home in a sports enthusiast's office or a coach's training space. 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.
