A vintage patent diagram for an early computing device fills the composition with precise technical drawings rendered in black ink on aged cream paper, its architectural blueprint style broken into numbered figures showing mechanical components, gears, and detailed cross-sections. The document bears handwritten signatures and bears the patina of history, capturing the austere elegance of nineteenth-century industrial artwork with its formal layout and meticulous line work. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
