VTG 1958 Masters of Deceit Hardback J Edgar Hoover Second Printing

Masters of Deceit: The Story of Communism in America and How to Fight It Second printing March 1958 Excellent vintage condition book. Please see photos. There is a stain of some sort on the back cover. I am assuming it is aged adhesive from the book hard cover as it is not on the adjoining page or dust cover.
