My original tumblr post was here. This cover image of the February 1956 issue Imagination Science Fiction was originally posted on Tumblr by pulpbizzare with the enigmatic (to me, anyway) text “3641-1852-10939.” It comes to us via Reginald Juice. The ISFDB entry for this issue is here, and identifies the artist as Lloyd Rognan.
