It's an excellent design, and I have the shirt, but I have it in Charcoal or Dark Grey or something. If I were to put this on my wall, I'd want it to have a significant impact and I doubt it could provide that with a light, slate grey. It also seems one would have to be much closer than on average to read what it had to say. I want this print, but in a darker color (not the font, of course, just the background).
