by Leo Morey

This is from 1930 and, as you can tell from the signature at the bottom of the picture, this cover was done by Leo Morey!  I like this cover and the way it mixes the plane, the ocean liner, and the tentacled-creatures.  Three ways to travel, two human and one alien.  Are the aliens abducting the plane or are they saving the pilot and maybe the ship?  We may never know.
