30 Mosques in 30 Days: An American Trip

Day 14: Denver
Shaykh Abu Omar, an 80-year-old Iraqi refugee, designed this sign and countless others like it that decorate his house. He has two signs in his bathroom pointing to the guest towel. There is one right on top of the guest towel pointing down, and another next to his personal towel that points to the other guest-towel sign.
