Try to find the spot where the photographer was standing.
The car is a 1934 Opel. I think you could date this photo slightly earlier, not because of the car, but because of the trousers of the young man crossing the street. He is wearing a so called plusfour, fashionable in the 1920s and early 1930s. I think they were out of fashion by 1940.
