Sepia-toned photo of the interior of the Detroit-Windsor Tunnel. An automobile drives away in the background. The road, curbs, ceiling, lights, and automobile have all been heavily retouched. A caption which was pasted on the verso reads:
Nirosta Reflectors Aid Tunnel Immumination
The only vehicular tunnel in the world, which connects Detroit and Windsor, Ontario, will open for traffic early in November. Like the tunnel itself, the Nirosta reflectors back of the lamps which make it as light as day, will last forever. They will never corrode, rust, tarnish, or lose their original high lustre.
