This image is of Burt Lake, Michigan during an afternoon showing the sun reflecting on the water as the camera points to the west, with the sun partially obscured at the top of the image.
There is no description on this card, only the caption: Sunset on Burt Lake
The image is not quite of a sunset, as the sun is not in close proximity to the horizon as would be expected in a typical sunset picture.
The lake is 17,00 acres of surface area, with a 73 feet maximum depth. It is located in Cheboygan County, the northernmost county in the Lower Peninsula of Michigan.
This image likely dates from the 1940s.

This image shows the rather rough road called Sand Dune Drive along the shore of Lake Superior on the Keweenaw Peninsula in the Upper Peninsula of Michigan.
There is no description on the back of this card. The caption on the bottom states:
Scenic view  Sand Dune Drive
Eagle Harbor Mich
–The sand beach in this area stretches for four miles from the unincorporated village of Eagle Harbor.
The auto shown indicates that the image likely dates from the 1940s.

This image is a view of the general store and gas station, with the lodge building in the background.
There is no description on the back of this card. The caption at the bottom states:
H&H General Store and O-Man-Me-King Lodge
Drummond Island, Mich.
–It is expected that in the intervening decades these buildings were replaced with more substantial structures, as the lodge on Drummond Island now is much newer.
The car tail light at the far left indicates that this image likely dates from the 1950s.
