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. Woven soft and absorbent, your artwork on the front with a crisp white back, made to order. Everyday art for the bathroom, a step past the plain store-shelf towel.
