It is part of their collection of "Men's Heraldic Graphic Tees", and item number #734840 if you want to order it online. The shirt is $15.00.
Archbishop Sheen once said that it seemed that everything Catholics "drop" as irrelevant in today's society, the world picks up and uses themselves. How right he was! I wonder if this shirt would be identified in a public school as conveying a religious message?
UPDATE: I went to a local Old Navy yesterday to buy the shirt, and they're on sale for only $8 each! Buy a bunch of them and sell them for $10 each as a fundraiser! Imagine what their corporate bigwigs would think if they saw this particular design sell like crazy? Might it get them to put out other designs that get the attention of Catholics?
