This prayer was composed by St. Charles Borromeo, the 16th century Milanese cardinal and Church reformer.  It asks our holy angel to be with us at the hour of death, for consolation at that hour from the Queen of Heaven, and for the grace to receive the Last Rites.  O my dearest Guardian Angel...do thou deliver (my soul) into the hands of its Creator and Redeemer, that with thee and all the Saints, it may gaze upon Him in the bliss of Heaven, love Him perfectly and find its blessedness in Him throughout eternity. 

Two different vintage images to choose from.  The prayer is exactly the same on both versions.

Printed on white cardstock.
