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 to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
