tiny student lampshade, emerlite type green & white cased glass shade vintage replacement

Banker's green and white cased glass lamp shade for a student / desk lamp... this is cute little thing, just 4 1/4" in diameter overall.

It's 3 1/4" tall, 3 7/8" across the fitter. It's a vintage piece without chips or damage, a good replacement shade for an old lamp.
