Cover of Science Wonder Stories 1, no. 6 (November 1929)

In red and black type the masthead features above a space scene. In the background, receding away is Earth. In the foreground there are two yellow flying saucers. The one closest has tentacle arms outstretched around a building, with the implication being that the craft and its occupants have stolen the structure and are making off with it for their own purposes. The cover advertises a three-hundred dollar prize for “the best short, SHORT story written around this picture.”
