We are in Putignano (Apulia - Italy) home to the longest carnival in the world (it is unsurpassed as it begins the day after Christmas!) and one of the oldest with its 629th edition <a rel="nofollow" class="external autonumber" href="https://www.carnevalediputignano.it/home/">[1]</a>.
Apart from the majestic allegorical floats, the "masked groups" are the popular folkloric soul of this kermesse and, as the ancient Latin motto says "Semel in anno licet insanire", this is what the girl on level zero of this anàglyph must be thinking  that she sees the person in front of her as if she were mirroring herself in hers!
