Some of us never "outgrow" comic books (...and thank goodness for that)...
And, with that rather tenuous introduction, we present out latest Separated at Mirth entry: WORLD'S FINEST COMICS #159 (DC Comics, Cover Date: June, 1966), cover by classic Superman artists Curt Swan and George Klein ...
...And DONALD DUCK ADVENTURES #23 (Gladstone Series II, Cover Date: December, 1993), cover by the great Don Rosa.
But, Joe... (you may find yourself asking), I see the "Separation" but, with our respective heroes facing such huge and overpowering adversaries, "Where's the Mirth?"
To this, I offer that each issue's adversaries are just SOOOO BIG, that even the standard comic book cover image space cannot contain them!
...An unusual, if not outright mirthful, use of the requisite issue title logo!
Of speculative interest: We know from previous comments, that Don Rosa read the Mort Weisinger-era Superman comics of which WORLD'S FINEST #159 is one - edited by Old Unca Mort himself.
So, it's possible that Rosa could even have (consciously or otherwise) been influenced by that cover, when creating his own for DONALD DUCK ADVENTURES #23.
Regardless of who may have influenced whom, we leave you with WORLD'S FINEST COMICS #159 and DONALD DUCK ADVENTURES #23... Separated at Mirth!
...It would have been a natural!
