The Marvel Family Comic Book

I came across this comic at ComicBookPlus. Captain Marvel is still somewhat popular but I confess I don't know much about him except that there were numerous versions of him.

In this comic three kids actually get changed to the Marvel Family when two of the kids say "Shazam" and one says the name of his hero, Captain Marvel He is the one who becomes Captain Marvel.

They all fly. I keep saying Shazam and Captain Marvel but nothing is happening.
