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 to order on smooth 100lb gloss paper, then rolled into a tube and shipped ready to pin, tape, or frame. Sized to fill a wall without filling the budget. The same independent-artist artwork you'd frame, at poster scale and poster price.
