Romantic Catholic (one of my favorite Catholic apparel shops) just designed a t-shirt in tribute to Pope Benedict XVI. And... it's only $10. Their stuff is quality and gorgeous. I know because some of my family members (including me) own other tees they sell.
And no... I was not compensated for promoting this. I just love the Holy Father, think this is a sweet idea, and know this is a great company and great price. Go shopping!
