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!
