It seems that everyone in the DC stable wanted to get in on the road to time travel including the humor line-up. The earliest that I’ve found so far in the Nov 1947 issue of All Funny Comics. Later, there were Bob Hope (in Bob Hope #43) and Jerry Lewis (in Jerry Lewis #43 and 54). In Bob’s story, he gets sent into the future by Carolyn Spooner. It also had a cover with Bob as a caveman. As I find others, I’ll list them in my time-travel comic books page.
This can’t be the stone age!—I’m just putty in the hands of a girl like you!
