Sandra Menace is the mother of the British version of Dennis the Menace. In one of history's most famous pop-culture coincidences, both the U.S. and UK versions of Dennis the Menace debuted on the exact same day: March 12, 1951. They were created completely independently of one another, with neither creator knowing the other character existed.
Trained on the current comic design. Her design has not been as consistent over the years as the US Dennis The Menace's mom, Alice Mitchell.
