From Orbis Catholicus Secundus

Band of brothers: Cardinal Spellman gives Communion at a Mass on the front during World War II. Corpus Domini nostri Jesu Christi custodiat animam tuam in vitam æternam. Amen. Receive Communion worthily, in the state of grace and fasting.

A reason why 1963 was a better time: the Pope had more style then too.
