The "Pius Pelican" is an ancient Christian symbol of Christ, and there is a verse dedicated to it in the St. Thomas Aquinas hymn, "Adoro Te Devote." A bit of that verse is in this design- in English, it is, "Pius Pelican, Lord Jesus, wash me with Your Blood."
This is a 3" tall water-resistant vinyl sticker. On cups, mugs, etc. occasional dishwasher use is ok, but hand wash for best results. Enjoy!
