This commemorative stamp set was issued by Vatican City in 1970 to promote the Church’s worldwide missionary message, reflected in the Latin phrase “In Universum Mundum” (“Into the Whole World”). The series features three striking designs: a blessing pope, the revered Infant Jesus of Prague, and a touching depiction of mother and child symbolizing global Christian outreach. Issued in denominations L.25, L.55, and L.100, the stamps highlight the universal nature of Catholic missions across cultures. The colorful artwork and religious symbolism make this set especially attractive for collectors of Vatican, religious, and mission-themed philately. Complete sets like this are valued for their cultural message and elegant design typical of Vatican issues.
