Surely Mighty Mouse time traveled in his comics many times, but the one that I ran across in
the MichiganState University library records is a 2-page text piece called “The Time
Machine” in issue 11. I haven’t read it, so I can’t say whether it’s fiction or
perhaps something on H.G. Wells’s story.
The mouse did save the day himself via time
travel in 1961 (Mighty Mouse 152). As I find other instances, I’ll add them to my
time-travel comics page.
