The First Appearance of BLACK ADAM (1945)

So who the heck is this Black Adam dude we're seeing on the TV trailers? Here's the skinny, from B.A.'s first appearance. This is from Marvel Family #1, published back in Dec. 1945. Near as I can discover, this is Adam's only appearance in Fawcett Comics, and is not seen again until DC revives him in 1977.
