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.
