This has to be the oddest announcement of a title's cancellation. As you can see, the cover asks "Is this the end of Spider-Man Comics Magazine?"
Well, nowhere on the inside does it say whether it was or not(it was), so what's the with coyness? What a way to leave a reader hanging!
The final collection of Lee/Romita ASM tales are:
"Beware...The Black Widow!", "Unmasked At Last!", and "The Reprehensible Riddle of the Sorcerer", which was the debut of Ross Andru as the new Spidey artist!
Also included is the Black Widow entry from the Handbook, courtesy Frank Miller.
...and that was it. No announcement, no goodbye, nothin'. Marvel tried the digest experiment with Spidey and a few licensed properties(which we'll talk about tomorrow), and then they, like DC, packed it in.
