From the back of the card:

"O glorious Saint Blase, who by thy martyrdom didst leave to the Church a precious witness to the faith, obtain for us the grace to preserve within ourselves this divine gift...Thou who didst miraculously restore a little child when it was at the point of death by reason of an affliction of the throat, grant us thy mighty protection in like misfortunes..."

This card is laminated.  The feast of St. Blase is February 3rd.
