...basic poster + the traditional "Cutting the pie" Νight.
"Pie" stands for "Vasilopita" (Greek: Βασιλόπιτα), and it is a New Year's Day bread or cake in Greece and many other areas in eastern Europe and the Balkans which contains a hidden coin or trinket which gives good luck to the receiver, like the Western European king cake. It is associated with Saint Basil's day, January 1st, in most of Greece, but in some regions, the traditions surrounding a cake with a hidden coin are attached to Epiphany or to Christmas.
