Loved the issue!
There was so much to like. That panel with Supes telling the kid to keep his secret was my favorite. I don't know how but that simple gesture felt like a classic Superman moment to me. Loved that.
The last panel was jaw dropping. The actual car! This has been discussed here. I like both the options. The car could be from another earth. Or it could be Superman's first appearance. (Could there be other options?) I think the issue implied the later:Superman's debut involved a car rather then a helicopter. But logically speaking who would drive this kind of car 10 or 15 years ago. In canon Superman debuted 15 odd years ago not the 30's.
