Keep Calm and Remember the Safe Word Metal Sign
Stiff upper lip, and all that.
Perfect dungeon/playroom decor, for those that swing in that particular direction.
8x10". These signs are custom-made for us in the U.K. They are aluminum, which means they can be hung outdoors with no fear of rust. At the same time, they're light enough to be hung inside using Command strips. Each has four mounting holes, one in each corner.
