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. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
