Hi
Re the "street photographer" bit:
I have quite a few family photos taken pre WW1 and late 1920s. (London) These are photos of the families mostly outside their front door , rarely in their yard or garden (in fact, only one. That's dated 1920)
I presume the photographer went from door to door, took his pics , developed them at home and then delivered to the customer.
Also, photographs of streets were often taken to be used as postcard images, often with the willing local children in the foreground and somebody's delivery cart for an extra bit of "animation".
But I suspect your Little Tich was of the first kind
