I lost interest in my crossover project on OUROBOROS DREAMS some time back, but though this one isn't great, it is one of the most peculiar.
In FEATURE COMICS #81 (1944)-- a comic whose headliner was the long-lived but nearly forgotten Doll Man-- a humorous character named Blimpy got himself shrunk to doll-size. So he calls Doll Man about his predicament, and the hero refuses to help because it would break "union rules."
On a totally unrelated subject, here's a late fifties cover from Simon and Kirby's THE FLY:
It's a pretty cool cover, unless one stops to wonder why a superhero who can fly is bothering to swing at the villains on a rope.
