This poster from the 1950s has been widely shared online since the 2016 election debacle, and DC Comics has an interesting look at the history of the image and message,
In 1949, DC (National Comics) produced this same image and text originally for a 12 x 18” brown paper school book cover that was distributed to schools by the Institute for American Democracy, an offshoot of the Anti-Defamation League. While the author of Superman’s reminder of the American creed is unknown, the art is believed to be by noted Superman artist Wayne Boring.
