This one comes from the Harvard Map Collection, from the 1989 series of Garfield & Friends.
Garfield hosts a TV show where he makes things up and says they are true.
Garfield claims that the state of Wyoming does not exist. In 1789, Arbuckle Vespucci, famous explorer, was working on his map of the United States and left out Alaska and Hawaii, which his cat put on. There was also one gap left out, and there were no more pieces. So the cat wrote in “Wyoming”, which was Italian for “no state here”.
