This 1970 Zephyr map, issued by the Naph-Sol Refining Co., of
Muskegon, Michigan, includes the Osceola brand, which had been
recently acquired by Naph-Sol. The map itself consists of the
official Michigan and Wisconsin highway maps issued by the
respective state departments of transportation printed
back-to-back and with Zephyr covers in place of the normal
state covers.
