Just added a new photo to the Toward The Unknown/XB-51 Gallery thanks to Doug Nelson: The cover of the April 1950 Air Trails Pictorial magazine with a pretty ominous XB-51. Looks more like something from Germany in WWII!
Update: Hank Caruso was kind enough to share that the artist of the magazine cover was Frank Tinsley (1899-1965). More of Frank’s art can be seen on Flickr.
