The Lockheed SR-71 Blackbird vintage metal sign measures 24 inches by 12 inches. The sign features an image of a Lockheed SR-71 Blackbird with a colorful sunset background. The sign is hand made in the USA using heavy 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 with a hand vintaging process to give the tin signs a more retro and nostalgic look and feel. This vintage antiqued metal sign has four grommeted holes for easy hanging.
