This title morphed into Top-Notch Laugh Comics, and was then acquired by Archie Comics. I don’t know whether there were any further adventures in time by Rand or others during the Top-Notch run.
That first issue had this Otto Binder story in which a farmer takes two archaeologists, Stoddard and Jackson, to a time capsule that’s so unusual it couldn’t possibly have been buried by any known civilization. They take it to the Archeological Institute where their boss instructs them to clean up the outside apparently believing that they’ll stop once it’s clean.
