On May 31, 1994, Vatican City issued a series of stamps devoted to the theme adopted for Europa 1994, "Europe and the Discoveries."
Professor Giovanni Contri designed the stamps. In the upper right comer appear the Papal Tiara and Crossed Keys. At the right appears the word EUROPA, and along the bottom appear CITTA DEL VATICANO and the value. The 750-lire value features a white thread to symbolize the continuity of human progress in the quest for knowledge, from the wheel to the atom.
The stamps are horizontal in format, measure 40.50 x 30.45 mm, and have a perforation of 13 3/4 x 13 1/4. Joh. Enschede of the Netherlands printed 600,000 complete series
on white chalky paper using the offset process. The stamps were issued in sheets of twenty.
