Tell That To The Marines!
James Montgomery Flagg (1877 – 1960) was an American artist and illustrator. He is most famous for his war effort posters but he also work for magazines, did cartoons, and even paintings. "Tell it to the Marines' is a catchphrase, originally with reference to Britain's Royal Marines, connoting that the person addressed is not to be believed i.e.gullible ("tell it to the marines because the sailors won't believe you"). but Flag changed it into a propaganda poster showing a variation of the phrase and an enraged recruit: if there's a wrong to be avenged, tell the Marines, because they will do something about it.
