The Republic of San Marino celebrates the International Day of Happiness with a philatelic set designed by Mirella Musri, an illustrator, an artist and a teacher from Argentina. The two stamps show four children from different ethnic groups playing together: they run on the earth (€ 0.95 value) and they ride a stylized swallow with Mount Titano in the background (€ 2.30 value).
The International Day of Happiness, established by the United Nations General Assembly on the 12th of July 2012, is celebrated on the 20th of March. UN Secretary-General Ban Ki-moon stated that the world needs a new economic paradigm that recognizes the parity between the three pillars of sustainable development: social, economic and environmental well-being are indivisible, together they define gross global happiness. Mirella Musri, who worked by Fabrica, Benetton research centre on communications, meets UFN’s aim to increase the creative quality of the stamps through the interaction of artists and designers from different cultures.
