This commemorative stamp set from Vatican City (1964) celebrates the historic apostolic missionary visit of Pope Paul VI to Bombay (Mumbai), India, during the International Eucharistic Congress. One stamp depicts a scenic view of Bombay with palm-lined roads and a monument representing the city’s landscape, while the other features a portrait of Pope Paul VI in prayerful gesture. The issue highlights the Vatican’s missionary outreach and the significance of the Pope’s visit to India. These stamps are notable for their historical connection between the Vatican and India and are valued by collectors of religious, papal, and international event philately.
