Lot (12) Vintage mixed Art Deco chrome chain necklaces Czech red green black depression glass beads

Lot (12) Vintage mixed Art Deco chrome chain necklaces with Czech green and red round and green and black marble melon depression glass beads. With chrome plated link chains and chromed clip barrel clasp closers. These necklaces are from new old stock, recently discovered in Jablonec nad Nisou (formerly Gablonz), the home of Czechoslovakian jewelry. 
These necklaces follow the Bauhaus style of the Jakob Bengel company in Germany whose pieces of jewelry were a mixture of chains and different glass or galalith plastic elements. The company is well documented as being a major exporter to Gablonz from where jewelry would be distributed around the world.
