A vintage bicycle dominates the upper half of this technical patent illustration, rendered in crisp white lines against a deep blue grid background, while detailed mechanical components and assembly diagrams fill the lower section with precision and clarity. The composition captures the methodical language of 19th-century industrial patents, with handwritten signatures and dated annotations completing the authoritative, historical aesthetic. 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.
