mod vintage amethyst glass hurricane shade set, rustic crackle glass candle shades

Set of two 1970s vintage amethyst crackle glass hurricane shades, not perfectly identical as these are hand crafted, hand blown glass. They're made to hold a pillar candle, or use on rustic candle holders, sconces, or a chandelier.

They're all in good condition, and all similarly sized. These measure about 8" tall x 3" across the fitter ends.

These might be Blenko, or maybe Mexican art glass? No marks or labels, so I'm not sure!
