Issued during the Sede Vacante period of 1978, this Vatican City commemorative set symbolizes the interregnum between pontificates. The design reproduces a stained-glass motif featuring the crossed Keys of St. Peter beneath the papal pavilion (ombrellino), rendered in three rich color variations. Printed by I.P.S. Roma and designed by E. Vangelli, these stamps are notable for their modern ecclesiastical art style and sharp intaglio detail. A classic Vatican thematic combining religion, heraldry, and papal history, highly sought by collectors of Sede Vacante and Vatican issues. Ideal as a complete matched set for advanced collections.
