A detailed patent drawing of a nineteenth-century steam locomotive engine dominates this composition, rendered in crisp white lines against a rich cobalt blue grid background. Multiple technical views show the engine from different angles alongside cross-sections and mechanical components, capturing both the ingenuity of industrial artwork and the romance of the steam age. 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.
