Charlton’s first issue of Space Adventures introduced Hap Holliday, the Time Skipper, who travels with Professor Eon Tempus to the far future to rescue Ula, queen of Futuropolis, from reptile people. The end of this installment assures us that we’ll learn more of Ula in the next issue, but alas, the second and final adventure of the Time Skipper was delayed until Space Adventures #3.

At the end of the Time Skipper’s first adventure, Hap Holliday and the professor were hoping to convince Queen Ula to accompany them back to the past, and it seems they succeeded, since Ula is with them on the splash page. But in their return trip (via the ever-staunch Timejumper), they overshoot their mark and end up in ancient Rome where the trio meets Cleopatra and tries to save Caesar.

Charlton’s Gorgo comic was inspired by the the 1961 movie of the same name Unlike the movie, however, the comic book Gorgo had one adventure in time when Dr. Hobart Howarth rescues Gorgo from YaPa* by sending the giant reptile back to the late Jurassic. Sadly, as a child, I bought only one Gorgo comic, which was not the time-travel issue, although that one issue I had was drawn by Steve Ditko, hooray!
* Yet another Pentagon attack

Although this one-page feature is title “Time Pocket,” it seems to be about travel to another dimension rather than through time.
