On March 12, 1951, Hank Ketcham’s Dennis the Menace comic strip first hit American newspapers.
Where it Gets Weird:
Just a few hours before Ketcham’s “Dennis the Menace” hit the nation, on the opposite side of the Atlantic, the first appearance of what went on to become cartoonist David Law’s most famous creation, “Dennis the Menace” comic hit newsstands.
The two comics strips both had the same exact name and were published at the same time.
Neither man knew or had any way of knowing, that there was an equivalent comic being developed elsewhere. No lawsuits were filed, the two cartoon characters had nothing in common and both went on to become immensely popular with their respective audiences.
