Cute sign! It's wood, and the weight of it attests to that, but it hangs easily with a keyhole opening on the back. The only thing I might offer as a "warning" to others is that the sign may be a darker green than what you see on your monitor. I expected a mottled sort of teal, but mine is definitely closer to a hunter green than true teal. Still works for our space, and it got a laugh out of my hubby, who can spend WEEKS in the bathtub. (Well, it feels like it, anyway.) Fun decor for the bathroom hog in your life!
