TLS – Typewritten Letter Signed, one page, 3 June 1968. Written on the official letterhead of the apostolic nuncio of La Paz, Bolivia (private mission?).  Touching condolence acknowledgment  to a monsignor-friend.  Reads:  If kind words were capable of filling the void left by the death of my mother, she would still be with us. But the loss is too severe; it came suddenly. I thought the good Lord would grant me the joy and fortune to long enjoy her motherly presence on this earth. The will of God is always merciful. Thank you for your condolences. Please continue to remember the blessed soul of my mother in your prayers.
