The Butler Eagle newspaper in Pennsylvania fired syndicated cartoonist Wiley Miller on Monday after a reader reported a hidden anti-Trump message in Miller's Sunday cartoon. The cartoon tells Trump to "go f*** yourself."

Here is the image of the Non Sequitur comic strip.

According to the paper's publisher, newspapers around the country printed the cartoon without having an opportunity to review it.

“A reader brought to our attention that one of the syndicated comic strips which appears in the Sunday Butler Eagle may contain a hidden message which was apparently placed there by someone in the creative department of the creator of the comic strip or the syndication which controls it,” said Ron Vodenichar, Eagle publisher and general manager. “Neither the Butler Eagle nor any other newspaper that includes this strip had an opportunity to remove it even if they had discovered it before distribution."

Wiley also acknowledged the hidden message on Twitter, alerting his followers to the "hide and find" game.

Some of my sharp-eyed readers have spotted a little Easter egg from Leonardo Bear-Vinci. Can you find it?
