The story 'The Very Thing That Happens' is quite interesting. It has a strange plot that keeps you guessing.
I would recommend 'The Flying Machine'. In this story, Edson's imaginative side really shines. It's about a flying machine that is not what you would expect, and the story unfolds in a very surreal and engaging manner. It shows his ability to create a whole new world within a short story.
One that stands out is 'The Man Who Made Chairs'. It has a unique take on creativity and the human condition. The way Edson describes the man's relationship with his chairs is both fascinating and thought - provoking.
