A technical patent drawing of a light bulb dominates this blueprint composition, rendered in crisp white lines against a deep blue gridded background. Three detailed cross-section views show the bulb's internal mechanisms and assembly details, accompanied by handwritten signatures and official patent markings in the classical scientific illustration style. A glossy-finished set of four, made to order. A bold way to bring an independent artist's work into the room without committing to a large piece, whether on the dining table or the bar at your next party.
