This is a sign for horses, horseback riding, and the riding arena. I have some extras that I'm selling. They have been installed outdoors. They were made by a professional sign maker, so they should last 10-15 years without fading. You can use them outdoors by attaching an aluminum support to the center and securing it with mortar. These are original products. They are 45 cm diagonally and 64 cm vertically.
