It's doubtful I would have come upon this story without Scott Shaw reviewing the issue in his old Oddball Comics column at Comic Book Resources. Thanks Scott!
Also, I plan on running into NYC for the NY Comic Con this Saturday, 2/7/09. My plan is to rummage through the used and abused golden age stacks for more of these sort of stories that appeared outside of the usual titles. Any readers of this blog who are also going and feel like hooking up, shoot me an email at the address in my profile.
