The other great thing about The Bronze Age was that we, as fans, had seemingly unlimited access to comics' great history. Not just in back issues, but also with those great 100pg Super-Spectaculars DC used to do, full of classic Silver and even Golden Age stuff from the likes of Lou Fine, Dan Barry & Jack Cole.
There was also a chance to read Mort Weisinger's brilliantly madcap Imaginary Stories, where, for just that one issue, literally anything could happen. Here's the best Imaginary Story of them all, written by Leo Dorfman, and drawn by Superman's greatest artist Curt Swan. There's very little actual dramatic conflict in this story, it's more like the comic equivalent of slipping into a warm bath, or having a nice cup of tea. Safe, comfortable, utterly insane and obeying nothing but it's own logic, it comes from a time when Supes was every kid's Super Big Brother.
It's completely charming and quite magical. Enjoy.
