This pin is really just great!  It features a Mary Medal, stamped into an embossed heart shape, with the prayer around the edge "O Mary Who Was Conceived Without Sin Pray for Us Who Have Recourse to Thee".  The heart dangles from a little stamped metal bow.  The pin was probably a First Communion gift, and would be a great piece to give or to wear.  It is a nice size, about 2" long from top of bow to bottom of heart.  The locking pin back is in great shape with no damage.
