Quarto in red cloth. 256 pages plus bibliography and index, illustrated by photos. The book celebrates the centennial of Denver's Union Station. The book is clean and bright and soundly bound but there is a previous owner name on the front pastedown under the jacket flap. The jacket has light edge wear and it is complete but there is a tear of about an inch at the bottom rear panel The packet of five maps, often separated from the book because it does not fit very well, is not present with this copy. Very Good in Very Good Dustjacket.
