It is a story from a comic book that had to be published before 1967. I remember a splash page which shows, in a bird's eye view, a bespectacled man climbing a sheer, rocky cliff face with a trail of people climbing behind him. Below is a narrow, stark valley or gorge in which a crowd of people are standing in front of a massive and tall set of wooden doors. Apparently the gates of Hades.
The story may have been slight humorous. I think it ends with him getting pitch-forked in the behind. I have looked everywhere. In all the on-line public domain comics that would reasonably have such a story.
