Jon's Random Acts of Geekery is your five days a week destination for old-school geekery!
Jon,The GCD reveals it's a reprint of Superboy (1949 series) #205. They list it's by Mike Grell, so it must be derived from an interior page for "The Legion of Super-Executioners". The villain is the Mesteren (the master).Hope this helps!
