Guide Dogs for the Spiritually Blind by Samuel Sheats on Redbubble. I used to own a T-shirt with a similar design and this slogan, “Guide Dogs for the Spiritually Blind”, 30 years ago. When I ventured out into the most dangerous areas of New York City, even with a large camera bag and on the subway late at night, I made it a point to always wear that shirt. No one ever bothered me. Did they think I was obviously too crazy to mess with? Perhaps. I make no guarantees for you, though! Available as apparel and other merchandise.
