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. Printed on clear acrylic and made to order in two sizes. A serving piece for the dinner party or a pop of color as a kitchen accent, carrying an independent artist's work instead of a big-box print.
