So here's that cheap unappreciated Neal Adams Superman.  I was showing this around in the Bronze Comics Forum:

How can you not love this?  Superman at the gates of Hell!  How'd that happen?  Where are those gates?  What did the lady do, and should Superman help her?

I'm going to find out and I'll report back!

Edit:  OK, I read it.  A few things I can say, Curt Swan interior art and a Batman Cameo.  But I can't describe the plot without revealing spoilers.  I can say that it's a good story!
