It's hard to say. You'd have to look at the background and details of the story. Sometimes there are elements that seem true but could be fictionalized for dramatic effect.
There are so many possible 'true stories' associated with a name like Elliott Winther. He could be an artist who overcame great obstacles to make a name for himself.

Definitely not. Mary Poppins is a work of fiction. It's a delightful tale that emerged from the creative mind of the writer, without any basis in real-life happenings. The fantasy and charm of the story are what make it so beloved.
