In Chapter 2 of Hemingway's A Moveable Feast, he recounts Gertrude Stein's telling him that one of his stories was inaccrochable and then using a simile: "That means it is like a picture that a painter paints and then he cannot hang it when he has a show and nobody will buy it because they cannot hang it either." (p.25, Restored Edition)
Now, what is the meaning of the simile? Whether or not the work is good, no one wants to see it. Ms. Stein actually told Hemingway that she thought the story, "Up in Michigan," was a good one. However, it was not something she enjoyed reading and believed that others would not want to read it.
