Technical line drawings of a football helmet patent fill a dark charcoal ground, rendered in white ink with the precision of an engineering schematic. Multiple views show the helmet from different angles alongside detailed cross-sections and component diagrams, creating a layered composition that reads as both scientific document and sports history. At home in a game room, man cave, or sports enthusiast's office. 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.
