A bird holds in its beak a shining wine glass, while to his feet there is a ring with ( probably ) a big diamond. In the writing at the foot of the page ( lines 4-5 ) one finds an explanation: Neanche un diamante brilla piu' di un bicchiere lavato con Pril 3 in uno Perfect ™. Lasciatevelo dire da chi di brillantezza se ne intende ./ Neither a diamond will brighten as more as a glass washed with Pril 3 in uno Perfect / Let it to say by one who is a connoisseur of bright things.
The image, as for itself, has not immediate understanding, except for anyone who recognizes the bird ( the magpie) and knows his habits ( to steal bright objects, for which he is called the thievish magpie). There is a hyperbole (identity by similarity ) in the thievish magpie that steals the wine glass. Even more, the thievish magpie with the glass in his beak becomes the expert that acts as testimonial ( identity by similarity, on the attribute "bright").
Has the average population as the target of this advertisement, all that knowledge? Has it even the willing to read all the writing? Is this writing exhaustive? Is there the risk of a hidden opposition such a tale (the magpie stealing the wine glass) and the reality (the power of the cleanser)?
