Query: How is this book "in the public domain" when it wasn't published originally until 1959?

This publisher claims to have reprinted this book as a public domain item copyrighted prior to 1923. That is impossible, as this book was first published in 1959. This edition, published by Nabu Press, is infringing on the copyright of the original publisher, as the book cannot by date be in the public domain.
