House ad for Superboy (1949 series) #159 (September 1969); printed in Wonder Woman #184 (September-October 1969)
Ad designed and lettered by Gaspar Saladino
*Because I hadn't found it yet. Instead, I'm still happy to have posted this house ad, which asked the musical question "Where's Flop?"
But right now, a super-gorgeous cover by the greatest hero of the Expanding Earth, Neal Adams!

This cover falls square into the theme of that old familiar comic trope: "This scene does not appear in this comic book!" There is no "rain of the Supermen" (see what I did there?). Superboy sends out four, count 'em, four Superboy robots around the world. And they never fall from the sky at the same time. However, this comic does feature the first DC Universe Earth-1 appearance of The Giant RKO Logos! Seriously, these things are taller than Italy. That means each of these gargantuan radio masts is more than 800 miles tall! Their giant footprint casts a shadow that withers over two billion bushels of crops! To build them took the entire mining output of Asia, Europe, and Africa for six hundred years! They extend to outermost layer of the atmosphere, the "exosphere!" (Thank you, Wikipedia, for that last fact.)
