This is "Airplane" by Kathleen Hunt. This scope is made of stained glass in the shape of a single wing airplane. There are two interchangeable object wheels of fused glass (propellers) so that you can reverse them to mix up the internal images. These scopes have a 3-mirror system, they measure 9-1/4"L x 9"W x 5"T and they are signed and dated by the artist. The scope bodies come in different colors of stained glass so you will want to call the store prior to your purchase to determine which colors we have in stock and to choose the one that is perfect for you.
