Large vintage Art Deco machine age style silver tone chrome abstract geometric brooch - three-dimensional, architectural design

Large vintage Art Deco style brooch in shiny silver tone chrome, with a streamlined three-dimensional space age shiny chrome design. The lighting for the photographs gives the surface a yellow/gold glow in places, but this is solely the lights, the brooch is completely silver tone.

I love the way the soft lines of a circle and curved metal surface have been combined with classic Art Deco angular aerodynamics in this design. This piece may have been produced during the Art Deco period, but there were many revival periods too in which it could have been produced, for example the 1980s.

The brooch is large in size with a length of about 3 inches and a width of about 2 1/4 inches. It is in very good vintage condition.
