This Keep Calm vintage tin sign measures approximately 18-inches by 12-inches. Unlike most tin signs, we design and make our signs in the United States using 24 gauge American steel and a process known as sublimation, where the image is baked into a powder coating for a durable and long lasting finish. We then perform a vintaging process by hand to give this sign an aged look and feel. This sign is drilled and riveted for easy hanging.
