That’s a remarkably unexciting cover on World’s Finest 56 (Jan/Feb 52).
It’s not a spectacular issue, either. The only story that stands out is the Tom Sparks one, and even that is not exceptional. Bob Brown and Dan Barry give Tom a phantom house to deal with, one that can be seen, but not touched.
As has become common in his stories, there are criminals at the core of the mystery. Usually Tom invents some device to triumph, but in this story it’s a matter of figuring out how the illusion of the house is created. I’m not sure if it would really work this way, but his explanation, complete with diagram, does impress me.
