Three technical drawings of a baseball helmet appear in white line-work against a charcoal chalkboard background, showing front, side, and rear views with precise patent annotations. The composition captures the functional geometry of the protective gear with the austere clarity of vintage industrial documentation. At home in a sports enthusiast's office or a baseball fan's game room. Printed on glossy aluminum and made to order, ready to hang with the hardware built into the back. Original artwork in a finish that holds its color and resists fading, not a quick print off a shelf.
