Hello.
Any particular car models you can make out in this photo?
It was taken in 1926 in Calgary, Canada.
Yes it was taken as a color photograph, a so-called "autochrome". Not colorized later.
There is a large collection of color photos - not artificially colorized photos - from around the world from the early 20th century. They are known as les Archives de la Planète (Archives of the Planet). There are no photos from the US there, but there are photos from Canada in 1926 - and there are cars in some of them.
The site is in the world's international language... French A bigger problem is that searching is cumbersome, if you click on the map, you can only browse through thumbnails - if you accidentally find an interesting photo there and want to see it full-size, note down its ID (like "A 49 308") and try to find it the right way. BUT: I strongly recommend browsing images the right way from the beginning.
The right way is: ignore the map and use only the menu of the left: Lieu -> Amerique -> Canada. You will then have a scrollable stream of photos *under* the map.
There are two scrollbars, the outer one is for the webpage and the inner one is for the stream of photos. You should find about 1000 photos from Canada there, if you see much less, you probably missed one of the scrollbars. "Telecharger" means "download" (the image).
