A vintage patent drawing depicts a steam locomotive in detailed mechanical cross-sections, rendered in sepia tones on aged paper with handwritten signatures and official notation at the top. Multiple engineering views show the locomotive from different angles alongside close-up diagrams of wheel mechanisms and mechanical components, creating a technical yet nostalgic composition that celebrates industrial 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.
