Snautzer, do you by any chance know which city is this? Is this modern looking building still existing?
The above photo is from the public LIFE-archives. An important clue is the "Goten Apotheke" in the ground floor of the corner building. There is a
pharmacy with the same name in Köln, Germany - I googled it but the location is different. Yes, there is a 5-6-storey building nearby, but it doesn't appear to be the same.
This looks like a very prominent modern boulevard constructed around the time of the photo: the trees are very small and all buildings are in the same modern style.
It would be interesting to have a today's view of the same place.
Cheers!
P.S. I found it by coincidence - this is Gdynia in Poland.
