You actually have two quite different documents, although both are Papal blessings.
The one with the photo of the Pope is an Apostolic Blessing bestowed on Leo C. Zeferetti. It is dated 19 December 1979, and the photo shows Pope John Paul II (who reigned from 1978-2005). The blessing was signed on the Pope's behalf by an Archbishop at the Vatican. Such blessings are fairly commonplace - they are granted on request for special occasions. Yours looks to be in rather poor condition. From the link given by Melda, the original recipient is still alive, but elderly.
The document in your second photo (headed "PAULUS VI") is more interesting. It was issued on 8 December 1965 ("VI ID. DEC. ANNO MDCCCCLXV") - yes, that means 8th December, not the 6th! - on occasion of the closing of the fourth and final session of the Second Vatican Council (1962-1965). The blessing was bestowed by Pope Paul VI, who reigned from 1963-1978. It is addressed to members of three internal Vatican organisations: the Roman Curia, members of offices responsible for governing the affairs of Vatican City, and the Vatican military guards. The Pope thanks them for their assistance during the Council sessions and invokes the Apostolic Blessing upon them now that the Council has concluded. The document bears the Pope's signature, but it is impossible to tell, from the photograph, whether the signature is original or not.
