1961 Italian postage stamp – Michelangelo’s Sibilla Eritrea

Here’s an interesting example of a vintage postcard design issued on the occasion of the XX National Philatelic Convention in Rome in 1965 (Convegno Nazionale Filatelico) which includes a 1961 Italian postage stamp within the design – in the carriage window there is a 30 lire stamp featuring the Sibilla Eritrea which was issued as part of a set of nineteen Michelangelo-themed stamps on 6 March that year.

The 15 lire stamp actually used on the postcard meanwhile was originally issued on 6 December 1964 to celebrate the 6th Stamp Day (6ª giornata del francobollo) and depicts six Italian sports stamps within its own design. Here it has been postmarked on the first day of the stamp fair – 20 February, 1965.
