The Science-Fiction Super-Model?

Comic books were a little different in 1950...

...as creators thought it was sufficiently entertaining...

...to have panel after panel...

...of Katy Keene exercising...

...so her body can be...

..."just right for the movies!"

And then we enter the science-fiction part of our tale, where we learn that we're apparently in an alternate universe:

Yeah, right.

Anyways, that leads away from exercise, and to:

"Katy Keene--The Fattening"!!!
