The souvenir sheet, made up of 3 values of 1.00€, celebrates the Expo Milano 2015. The event will begin on the 1st May 2015 and its aim is to offer a new model of development and a new idea of cooperation. The Republic of San Marino will take part with its own booth by the Bio-Mediterraneum Cluster. The designer Mauro Vincenzo Bubbico, Professor of Visual Communication Design at the Isia in Urbino, is a master of design oriented towards environmental and social education. The theme of the Expo ”Feeding the planet, Energy for life” is shown through three figures that represent the work of the artisan, the sun and the earth that make the miracle of life come true. The first stamp depicts a bunch of grapes symbol of wine, the second one shows an olive branch symbol of oil and the third one represents three ears of wheat. The gold foil on the souvenir sheet ennobles the universal message of the Expo.
