During the Great War, from 1914-18, a new kind of art flourished. Hand crafted creations from gifted soldiers and army personnel became known as trench art. They used whatever material was at hand�bullet shells, wood, and fabric, during an era when planes were built from fabric on a frame. Popular fabrications included lighters and clocks made in all shapes and sizes. Our aluminum propeller clock was probably designed by an airplane engineer at a time when aluminum was only used for engines and small parts. A base with an art-deco feel sets off a truly charming little clock with a sense of history. Battery included.
