Steve dug into this, and found out something similar to what I did, there doesn't seem to be any other photos of this on the internet, and he spent a couple hours to get the following info, which I want him to know I appreciate a lot!
The temporary building was a temporary display promoting the newly refurbished Ford Rotunda in Dearborn, and displays on the 50 years of Ford in general. It was located at the corner of Washington Boulevard and Michigan Avenue in Detroit.
The little blue building contained displays of the 'new' Rotunda designed to entice the locals to travel the 8.4 miles to Dearborn to see it in person. The blurb on each side says (I think) "Visit The New Ford Rotunda Opening on June 16."
That's the statue of General Alexander Macomb in front of it, and the tall building in the extreme background is the Book Tower (built as the Book Cadillac Hotel, and now the Westin Book Cadillac Hotel). The Book Tower Garage and the Complete Home Outfitters to the left appear to be gone.
The Rotunda was originally built in Chicago for the 1934 World’s Fair and after the fair was dismantled and relocated in Dearborn, and redesigned to resemble four gears stacked in decreasing sizes. It reopened in 1936.
In 1942 the Rotunda was closed and converted into office space and school for the Army Air Corps. After the war it sat empty until 1952, when remodeling began in anticipation of the 50th anniversary of the Ford Motor Company in 1953.
After it reopened, the Rotunda became the fifth most popular tourist destination in the country in the 1950s. It burned down in November 1962
