Vintage ivory parchment lamp shade w/ pressed flowers and butterflies

Vintage parchment lamp shade covered with real pressed flower specimens and butterfly mounts. This is very nicely done, it's probably 50s, 60s or 70s vintage, but would also be in keeping with a style or a much older or even antique lamp.

We think this has made to fit over a glass lamp chimney shade with the 4" diameter center ring. The shade is 10" in diameter across the bottom rim, and is 5 1/2" tall overall.
