20 lire Fountain, St. Peter's Square single
On May 22, 1975, the Vatican issued a series of stamps featuring images of fountains in Vatican City. The series, also celebrating European Architectural Heritage Year, is composed of six values.
"POSTE VATICANE" and the respective value appear along each stamp's border. The 20-lire stamp portrays one of the fountains in St. Peter's Square, with a view of the Basilica in the background.
The six stamps were designed by Professor Lino Bianchi Barriviera and were engraved by E. Donnini, R. DiGiuseppe, and F. Tulli. The stamps are horizontal in format and measure 48 x 40 mm. Printed in sheets of twenty-five, they have perforations of 14. The stamps were printed in offset and chalcography in two colors on white glazed paper. The Polygraphic Institute of the Italian State printed 1,600,000 complete sets.
