Mackinaw City, Michilimackinac State Park, Mackinaw Lighthouse (Michigan)
As a reminder, we try to follow the spelling used on the postcards themselves. Two of these unused 1967 Hiawatha cards 46781-H (30433) are available. They say this lighthouse was built in 1872 and in operation until 1957, with “the possibility that a marine museum may some day open.” At least one internet source says the lighthouse went into operation in 1892, and that it did indeed reopen as a museum in 2004.
