Illusions in Advertising

I found these videos on youtube. They are quite interesting and funny. I especially like some of them (the bag with the picture of a girl is opening her mouth and some people hold it ). Here raises the question in these videos: At the end, they wrote "Many more illusions in advertising Gestalt:" I wondered is this gestalt or not? I think these advertisings are much more composited rather than gestalt. It's just my thought. If you have any different thougths, just leave a comment.
