An image display craft (10) for outdoor advertising. The craft is lighter than air, such as a dirigible airship (12), and has flat projection surfaces (16) on each of its sides. Variable static or moving images, such as advertising images or other messages, are projected onto the sides of the craft by projectors (30) which are positioned on booms (22) that extend laterally from the craft. As the airship moves around the sky the image is visible on the exterior of the craft to observers on the ground.
