Good catch - if that is a fact it's not nit-picking.
I just posted the meme as I found it on Google and don't know if that photo is or isn't Detroit so I bow to your correction.
Either way I believe the meme does make the point.
Below is a photo that is quite similar that I just found with a search for "Aerial View Of Detroit 1945". It is captioned as follows:
"Detroit aerial view (May 24, 1946) - Officially Licensed Detroit News Puzzle".https://fathead.com/products/msc-5040-00090-112
