vintage glass lamp or light shade pair holophane style prismatic waffle pattern clear glass

Pair of unmarked vintage glass lamp shades... possibly hand blown glass made in Mexico, these have a few bubbles in the glass and a heavy weight that we generally see in Mexican art glass, 70s or 80s vintage.

They're very close as a match goes, but not machine made identical, because of the bubbled texture creating a slight color variation.

They have a waffle or cross hatch prismatic pattern, and stand 5" tall. They measure 7" across the wide end, 3 1/4" across the fitter.
