Superman trapped in a dimension where there's no passage of time.
Greetings.
I am wondering if anyone would happen to know which comic this occurred in. Superman is trapped by an enemy in such a way that there is no time in which to perform an escape. I never saw the next issue, and have always wondered what happened. I think the issue was published in the '70s. Unfortunately, I've had no luck looking on-line, probably because I'm not entering the appropriate search criteria.
Any help would be greatly appreciated.
