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 soft, lightweight polyester with hand-sewn edges and made to order. Original artwork at room scale, light enough to hang almost anywhere and move with you.
