My original tumblr post was here. This April 1948 cover of Thrilling Wonder Stories contains the text “The Faceless Men, a complete novel by Arthur Leo Zagat. Carl Jacobs, Arthur J. Burks, George O. Smith, Frank Belknap Long. Now 148 Pages! Share in Canada’s Future: Buy Savings Bonds.” It was originally posted at furious ape!.
“Thrilling Wonder” published twenty-five issues of a Canada edition; reportedly they were identical in content to their American counterparts except for the pages being taller.
This cover was also the April 1948 American edition: http://www.philsp.com/data/images/t/thrilling_wonder_stories_194804.jpg
