I just ran across this Ditko story in STRANGE TALES 76, August 1960.

"I Found The Mad Universe", 5 pages.

I love the bits of irony and twist endings in these pre-Marvel (1958-1963) stories by Lee with Ditko, Heck, Kirby/Ayers and others, how they evolved into the Marvel style of storytelling. In many ways I prefer these shorter works. With clear similarities to the TWILIGHT ZONE and OUTER LIMITS series.
A few artists like Williamson, Wildey, Colan, Reinman, Sinnott and others were only brief collaborations in this period, but an interesting contrast to the Lee/Kirby/Ayers or Lee/Ditko or Lee/Heck work.

Although in this case and in many stories, it appears to be Ditko story and art, without Lee.
