A technical blueprint rendered in classic blue and white shows detailed mechanical drawings of an early computing device with multiple cylindrical components, gears, and circular mechanisms arranged across the page. The composition combines engineering precision with historical significance, presenting cross-sections and top-down views that capture the intricate mechanical thinking of late 19th-century innovation. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
