I'm starting to think the mystery building with the tile roof might not have been in Detroit, but possibly in some other town and state. The reason I say this is because ...
This picture is described as circa 1920-1925 - Which the line of trucks seem to support.
And even though this next picture was not dated, which is from the same angle as the last picture, the cars appear to be late 1930s or early 1940s. Notice the glass and the word Ginger Ale is missing from the sign, which might indicate the sign was either being taken down or possibly repaired. ???
In other words ...
The building seems to have gone unchanged between the 1920s and 1940s. And because the new ten story building was completed in 1941, I don't see a time period when the tile roof building could have fit into the mix. I seriously doubt the tile roof picture is from the late 1800s or early teens, although I suppose it could be. ???
The only other thing I can think of to explain the tile roof building are bits and pieces of unconfirmed information that mention a Vernor's soda fountain that was located "across the street" from the new ten-story building that was completed in 1941. Maybe, just maybe the tile roof building was that soda fountain. ???
Here's 2 pics of Woodward looking south, Similar location of my old Black & White pic I posted the other day & one looking north from the very end of Woodward. Where Hart Plaza park is now is where Vernors was 100+ years ago.
The end of Woodward at Jefferson nowadays. Hart Plaza at right & Reneaisance Center Building at left. I heard when the were building the Reneaisance building in 1975 they found/unearthed tons of old 1850-1890's bottles. my Cobalt blue ten pin Teller's Mineral Water came from that find. Hart Plaza is where Vernors & many old streets & buildings once stood. now long gone. LEON.
