Nick Cardy had nothing to do with this cover. Possibly he submitted one, noting it on his own records, but if so, his went unused. Cardy didn't draw the cover published.
My only question on the pencilling and inking here is whether Bill Draut might have helped pencil—note the head of the boy on our left. But going by his legs and so on, the main artist is Joe Orlando. I can't find the slightest trace of Nick Cardy's style in pencils or inks.
Does anybody see it here?
By the way, I ran across the GCD entry on HOM 174 when I glanced at the earlier issues, to find that attributions on Dial H for Hero that had been passed along from my twenty-year-old lists had been replaced—and I was still given the "credit." In fact, I had listed only the writers of 156-165 and 173, if I recall correctly; I didn't read the Binder and Dick Wood issues until March 2012, but I supposedly attributed them to Dave Wood. I certainly didn't credit 173 to Jack Miller. But somebody heard second-hand that Miller had taken over the feature, so blithely altered the entry from Dave Wood to Miller but left me still the source. (My latest Dial H list is a few posts back.)
