Arguments work on us psychologically and cognitively, triggering emotions and thoughts. Implicit arguments may not look like arguments at all. Consider a bumper sticker, a billboard, a poster, a photograph, a cartoon, a vanity license plate, a T-shirt message, an advertisement, a poem, or even a song lyric. Like explicit ones, implicit arguments persuade their audiences toward a certain point of view.
Find such an image, post it here, and in a sentence or two explain the argument that it implies.
