We are not aware of any separate offprints of this paper from the Conference. Either there were separates and Shannon gave them all out, or he never received any and made copies for his file to distribute when asked. His Maze-solving machines were fascinating to the average person as well as computer scientists trying to figure out how these challenges might be overcome. Page 2 shows a large figure of the maze layout.
