I am the sculptor of this piece. It is a small sculpture, approximately the size of Ernest Hemingway's hand. It is available for purchase.

A Canary for One by Ernest Hemingway was first published in the April 1927 issue of Scribner’s Magazine, and in Hemingway’s collection Men Without Women. .The story is highly autobiographical, drawing on Hemingway’s own train journey across France as his marriage to his first wife, Hadley Richardson, was breaking down.

Enjoy!
