This is again an image similar to one previously posted some months ago. It is obviously the same location from the prominent ‘bulge’ of water near the center of the falls present in both pictures.

The people shown in the photo at lower left are wearing clothing that indicates this image is from the 1940s. Close examination of the picture reveals another person on a ledge just behind the falls.

Tahquamenon River Tour Boat, Newberry, Mich.
This is another image of a boat featured some months back. This image is closer in and in black and white, but otherwise the images are remarkably similar in that the boat does not appear to have been replaced, and the tourist still occupy the usual locations.

The boat itself is also called the Tahquamenon, as indicated by the name sign visible in the picture.
The brown marking in the upper right is damage from a decomposed rubber band. This image is hard to date, but is likely from the 1940s.
There is no description on the back.
Highway 115 Milepost, Frankfort, Michigan
This is the somewhat overbuilt signpost for Michigan highway M-115, which has one end in central lower Michigan and continues to the northwest where it ends at this sign.
The highway was originally earthen pavement when first constructed in 1929, but by the mid-30s the state was repaving the existing sections with asphalt and extending the highway with gravel as well.
There is no description on the back of this card. The auto in the picture, along with the initial construction date, indicate that this photo is from the 1930s.
City of Munising Auto Ferry, Mackinaw City, Mich.
This clearly marked ship is the City of Munising, once owned and operated by the Pere Marquette Railroad and converted by the state of Michigan to ferry autos across the Straits of Mackinac.
While there are passengers clearly visible on the decks of the ship, the amount of distance the hull is above the normal waterline indicates this ship is probably near empty.
This card was used, and is dated June 21, 1939.
Ann Arbor Railroad Ferry, Frankfort, Michigan
This ship though similar to the previous images, was owned and operated by the Ann Arbor Railroad, used them to transport railroad cars across Lake Huron and Lake St. Clair into Canada.
The signboard next to the bridge indicates it is the Ann Arbor, but the number of the ship is too faint to make out.
This card was used and is dated August 3, 1949.
Ferry Landing, Mackinaw City, Michigan
This image shows the ferry landing at Mackinaw City, MI, emphasizing the line of cars waiting to embark for the trip across the Straits of Mackinac. There was no bridge at the time of this photo, and the famous Big Mac bridge would not be completed for another nine years.

There is no description on the back of this card. The identity of the ship shown is unknown.
This card is dated 1948.
City of Cheboygan Ferry, Mackinaw City, Michigan
This card features the car/passenger ferry called City of Cheboygan, a one time rail ferry of the Ann Arbor Railroad that was converted to automobile carriage in 1937.

There is no description on the back of cards from this era, only the writing shown on the front.
As indicated in the image, this photo is from 1948.
Greyhound Post House Restaurant, Mackinaw City, MI
This is an interior view of the restaurant located in the Greyhound Post House and bus station in Mackinaw City, Michigan.

This carefully staged photograph shows the typical accoutrements of a table at a mid-1940s diner: the napkin dispenser, salt and pepper shakers, and a sugar dispenser. These are curiously all clustered carefully in one corner of each table, where in normal use they usually found their way to the center.
The slider shelf on the left hand counter indicates this was a cafeteria style service system. There is a small souvenir counter in the back, and a juke box on the right of the fireplace.
There is no description on the card.
Greyhound Post House, Mackinaw City, Michigan
This image shows the exterior and parking lot of the Greyhound bus station in Mackinaw City, MI as it looked in the 1940s. It served as more than just a bus station, as there was a restaurant and showers there as well.

The busses in service at the time are visible in the far right background, next to the sign indicating where additional accommodations and services could be found. The cars in the picture clearly point to the 1940s for this photo. Greyhound no longer serves Mackinaw City, and this building appears to be gone.
There is no description on the back.
Wilderness Park, Mackinaw City, MI
This image begins a series of black and white images of the backwoods and bays of Michigan. This is an image of a stand of white birch trees in Wilderness Park, Mackinaw City, Michigan.

The park is over 8,000 acres and covers the most northerly point of land on the lower peninsula of Michigan, looking out over the upper reaches of Lake Michigan. This image likely dates from the 1940s. There is no description on the back.
