A very detailed and colorful mobile identification device. Flat, lithographed. When the middle is spun, a silhouette an unidentified plane is shown at the top. Certainly many dozens of planes identified. In very fine condition barring center rivet fastener coming loose. This can be done with a paper fastener for a few cents. Has seen some use. Appendages both bent. Overall pretty clean. Some minimal wear throughout. Still bright and colorful.
