Exactly were in the City of Detroit, Michigan, the three parking lots in this photo are located is unknown, but it might be safe to say that all were close to downtown. After a quick look at the lead photo, you might think that there are only two lots, but the large and tall light-colored building in the background on the left is a parking garage that also has a small open area for cars on the roof.
In the first photo below just in front of the parking garage is the another parking lot. The second and third images below show enlargements of the left and right-hand sides of the third facility across the street from the other two. The last shot shows an additional section of the third lot separated by an alleyway between the two.
Note the top on the light-colored Buick convertible on the right-hand side of the third lot. Tell us what you find of interest in the early-1950s photographs courtesy of the Wayne State University Libraries.
