Wupper Airlines are wooden, bouncing mobiles that brighten the hearts of kids and adults! They are named after a river called Wupper in the town of Wuppertal, Germany. Windwheel (Red): This is a whimsical action figure that hangs from a long spring, bobbing up and down when gently tugged, causing the wind wheel on the boat to spin. The spring can be attached to any common ceiling hook. It is a well made, high-quality mobile designed in Germany. It is made of wood. The boat contains a man wearing a scarf, an old-fashioned aviator helmet and looking through a spyglass. The spring has a stretch in it which when pulled on makes the colorful wind wheel spin.
