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. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
